This introduces a slight behavioral change to rmfb. Instead of
disabling a crtc when the primary plane is disabled, we try to
preserve it.
Apart from old versions of the vmwgfx xorg driver, there is
nothing depending on rmfb disabling a crtc.
Vmwgfx' and simple kms helper atomic implementation rejects CRTC
enabled without plane, so we can do this safely.
If the atomic commit is rejected by the driver then we will still
fall back to the old behavior and turn off the crtc.
Changes since v1:
- Restart completely when rmfb with crtc on fails (Sean Paul).

Since drm_edid_to_eld() knows the connector type, we can set the type in
ELD while at it. Most connectors this gets called on are not DP
encoders, and with the HDMI type being 0, this does not change behaviour
for non-DP.
For i915 having this in place earlier would have saved a considerable
amount of debugging that lead to the fix 2d8f63297b ("drm/i915: always
update ELD connector type after get modes"). I don't see other drivers,
even the ones calling drm_edid_to_eld() on DP connectors, setting the
connector type in ELD.

We want to remove uses of do_gettimeofday() from the kernel since the
resulting timeval structure overflows in 2038. This is not a problem for
this particular use, but do_gettimeofday() is also not an appropriate
method for measuring time intervals, since it requires a conversion into
microseconds and is complicated to work with.
ktime_get() is a better replacement, as it works with the monontonic
kernel timebase and requires a minimum of computation.
I'm slightly changing the output from microseconds to nanoseconds here,
to avoid introducing a new division operation. This should be fine
since the value is only used for debugging.

This ioctl will allow us to purge inactive userspace buffers when the
system is running out of contiguous memory.
For now, the purge logic is rather dumb in that it does not try to
release only the amount of BO needed to meet the last CMA alloc request
but instead purges all objects placed in the purgeable pool as soon as
we experience a CMA allocation failure.
Note that the in-kernel BO cache is always purged before the purgeable
cache because those objects are known to be unused while objects marked
as purgeable by a userspace application/library might have to be
restored when they are marked back as unpurgeable, which can be
expensive.
