pxa_camera: remove init() callback

pxa_camera init() callback is sometimes abused to setup MFP for PXA CIF, or
even to request GPIOs to be used by the camera *sensor*. These initializations
can be performed statically in machine init functions.

The current semantics for this init() callback is ambiguous anyways, it is
invoked in pxa_camera_activate(), hence at device node open, but its users use
it like a generic initialization to be done at module init time (configure
MFP, request GPIOs for *sensor* control).

V4L/DVB: Fix VIDIOC_QBUF compat ioctl32

When using VIDIOC_QBUF with memory type set to V4L2_MEMORY_MMAP, the
v4l2_buffer buffer gets unmodified on drivers like uvc (well, only
bytesused field is modified). Then some apps like gstreamer are reusing
the same buffer later to call munmap (eg passing the buffer "length"
field as 2nd parameter of munmap).

It's working fine on full 32bits but on 32bits systems with 64bit
kernel, the get_v4l2_buffer32() doesn't copy length/m.offset values and
then copy garbage to userspace in put_v4l2_buffer32().

This has for consequence things like that in the libv4l2 logs:

libv4l2: v4l2 unknown munmap 0x2e2b0000, -2145144908
libv4l2: v4l2 unknown munmap 0x2e530000, -2145144908

The buffer are not unmap'ed and then if the application close and open
again the device, it won't work and logs will show something like:

libv4l2: error setting pixformat: Device or resource busy

The easy solution is to read length and m.offset in get_v4l2_buffer32().

V4L/DVB: firedtv: do not DMA-map stack addresses

This is a portability fix and reduces stack usage.

The DMA mapping API cannot map on-stack addresses, as explained in
Documentation/DMA-mapping.txt.  Convert the two cases of on-stack packet
payload buffers in firedtv (payload of write requests in avc_write and
of lock requests in cmp_lock) to slab-allocated memory.

We use the 512 bytes sized FCP frame buffer in struct firedtv for this
purpose.  Previously it held only incoming FCP responses, now it holds
pending FCP requests and is then overwriten by an FCP response from the
tuner subunit.  Ditto for CMP lock requests and responses.  Accesses to
the payload buffer are serialized by fdtv->avc_mutex.

As a welcome side effect, stack usage of the AV/C transaction functions
is reduced by 512 bytes.

Alas, avc_register_remote_control() is a special case:  It previously
did not wait for a response.  To fit better in with the other FCP
transactions, let it wait for an interim response.
