drm: Don't overwrite user ioctl arg unless requested
Currently, we completely ignore the user when it comes to the in/out
direction of the ioctl argument, as we simply cannot trust userspace.
(For example, they might request a copy of the modified ioctl argument
when the driver is not expecting such and so leak kernel stack.)
However, blindly copying over the target address may also lead to a
spurious EFAULT, and a failure after the ioctl was completed
successfully. This is important in order to avoid an ABI break when
extending an ioctl from IOR to IORW. Similar to how we only copy the
intersection of the kernel arg size and the user arg size, we only want
to copy back the kernel arg data iff both the kernel and userspace
request the copy.

drm/nouveau/bus: remove cpu_coherent flag
This flag's only remaining function is to ignore the uncached flag for
BOs on coherent architectures.
However the reason for allocating an object uncache on a non-coherent
architecture (namely because the cost of doing explicit flushes/
invalidations is higher than the benefit of caching the data because
accesses are few and far between) should also apply on architectures for
which coherency is maintained implicitly. Thus allocate coherent objects
as uncached on all architectures.

drm/nouveau/secboot: lazy-load firmware and be more resilient
Defer the loading of firmware files to the chip-specific part of secure
boot. This allows implementations to retry loading firmware if the first
attempt failed ; for the GM200 implementation, this happens when trying
to reset a falcon, typically in reaction to GR init.
Firmware loading may fail for a variety of reasons, such as the
filesystem where they reside not being ready at init time. This new
behavior allows GR to be initialized the next time we try to use it if
the firmware has become available.

drm/nouveau/clk/gm20b: add glitchless and DFS support
This patch adds support for advanced features supported by the
Noise-Aware PLL of Maxwell. Glitchless switch allows the PL field to be
updated without disabling the PLL first if the SYNC_MODE bit of the CFG
register is set.
More significantly, DFS allows the PLL to monitor the actual input
voltage and to dynamically lower the output frequency accordingly. This
allows the clock to be more tolerant of lower voltages.
These improvements are only supported for Tegra speedos >= 1.
Also add the voltage table that is suitable for GM20B's NAPLL. This
change needs to be done atomically for the right voltages to be used by
the clock driver.
v2. Fix build on non-Tegra platforms

Also make the MNP programming functions take the PLL parameters as
