[media] dvb-frontends/stv0367: add Digital Devices compatibility
This - in conjunction with the previous changes - makes it possible to use
the STV0367 DVB-C/T demodulator driver with Digital Devices hardware having
this demodulator soldered on them (namely CineCTv6 bridges and some earlier
DuoFlex CT addon modules).
The changes do the following:
- add a third *_attach function which will make use of a third frontend_ops
struct which announces both -C and -T support (the same as with DD's own
driver stv0367dd). This is necessary to support both delivery systems
on one FE without having to do large conversions to VB2 or the need to
select either -C or -T mode via modparams and the like. Additionally,
the frontend_ops point to new "glue" functions which will then call into
the existing functionality depending on the active delivery system/demod
state (all used functionality works almost OOTB).
- Demod initialisation has been ported from stv0367dd. DD's driver always
does a full init of both OFDM and QAM cores, with some additional things.
The active delivery system is remembered and upon switch, the Demod will
be reconfigured to work in OFDM or QAM mode (that's what the ddb_setup_XX
functions are used for). Note that in QAM mode, the DD demods work with
an IC speed of 58Mhz. It's not very good to perform full reinits upon
Demod mode changes since in very rare occasions this can lead to the I2C
interface or the whole Demod to crash, requiring a powercycle, thus the
flag to perform full reinit is set to disabled.
- A little enum is added for named identifiers of the current Demod state.

Currently, if_khz is set and provided using the configuration var in
struct stv0367_config. However, in some constellations, the value might be
different for differing channel bandwidths or even -T and -C operation.
When e.g. used in conjunction with TDA18212 tuners, the tuner frontend

be made, and if the tuner provides it, use it whenever needed.

[media] dvb-frontends/stv0367: add flag to make i2c_gatectrl optional
Some hardware and bridges (namely ddbridge) require that tuner access is
limited to one concurrent access and wrap i2c gate control with a
mutex_lock when attaching frontends. According to vendor information, this
is required as concurrent tuner reconfiguration can interfere each other
and at worst cause tuning fails or bad reception quality.
If the demod driver does gate_ctrl before setting up tuner parameters, and
the tuner does another I2C enable, it will deadlock forever when gate_ctrl
is wrapped into the mutex_lock. This adds a flag and a conditional before
triggering gate_ctrl in the demodulator driver.

[media] v4l2-core: Use kvmalloc() for potentially big allocations
There are multiple places where arrays or otherwise variable sized
buffer are allocated through V4L2 core code, including things like
controls, memory pages, staging buffers for ioctls and so on. Such
allocations can potentially require an order > 0 allocation from the
page allocator, which is not guaranteed to be fulfilled and is likely to
fail on a system with severe memory fragmentation (e.g. a system with
very long uptime).
Since the memory being allocated is intended to be used by the CPU
exclusively, we can consider using vmalloc() as a fallback and this is
exactly what the recently merged kvmalloc() helpers do. A kmalloc() call
is still attempted, even for order > 0 allocations, but it is done
with __GFP_NORETRY and __GFP_NOWARN, with expectation of failing if
requested memory is not available instantly. Only then the vmalloc()
fallback is used. This should give us fast and more reliable allocations
even on systems with higher memory pressure and/or more fragmentation,
while still retaining the same performance level on systems not
suffering from such conditions.
While at it, replace explicit array size calculations on changed
allocations with kvmalloc_array().
Purposedly not touching videobuf1, as it is deprecated, has only few
users remaining and would rather be seen removed instead.

[media] davinci: vpif: adaptions for DT support
The davinci VPIF is a single hardware block, but the existing driver
is broken up into a common library (vpif.c), output (vpif_display.c) and
intput (vpif_capture.c).
When migrating to DT, to better model the hardware, and because
registers, interrupts, etc. are all common,it was decided to
have a single VPIF hardware node[1].
Because davinci uses legacy, non-DT boot on several SoCs still, the
platform_drivers need to remain. But they are also needed in DT boot.
Since there are no DT nodes for the display/capture parts in DT
boot (there is a single node for the parent/common device) we need to
create platform_devices somewhere to instantiate the platform_drivers.
When VPIF display/capture are needed for a DT boot, the VPIF node
will have endpoints defined for its subdevs. Therefore, vpif_probe()
checks for the presence of endpoints, and if detected manually creates
the platform_devices for the display and capture platform_drivers.

colorimetry parameters.
If the field order is set to ANY, choose the currently set field order

Scaled output is limited to 1024x1024 resolution. Output frames
