Rockchip Socs have GPU, we need allocate GPU accelerated buffers.
So add special ioctls GEM_CREATE/GEM_MAP_OFFSET to support
accelerated buffers.

Commit ab8f58ad72 ("PM / devfreq: Set min/max_freq when adding the
devfreq device") initializes df->min/max_freq with the min/max OPP when
the device is added. Later commit f1d981eaec ("PM / devfreq: Use the
available min/max frequency") adds df->scaling_min/max_freq and the
following to the frequency adjustment code:
max_freq = MIN(devfreq->scaling_max_freq, devfreq->max_freq);
With the current handling of min/max_freq this is incorrect:
Even though df->max_freq is now initialized to a value != 0 user space
can still set it to 0, in this case max_freq would be 0 instead of
df->scaling_max_freq as intended. In consequence the frequency adjustment
is not performed:
if (max_freq && freq > max_freq) {
freq = max_freq;
To fix this set df->min/max freq to the min/max OPP in max/max_freq_store,
when the user passes a value of 0. This also prevents df->max_freq from
being set below the min OPP when df->min_freq is 0, and similar for
min_freq. Since it is now guaranteed that df->min/max_freq can't be 0 the
checks for this case can be removed.
Fixes: f1d981eaec ("PM / devfreq: Use the available min/max frequency")

The series vop of VOP_FULL framework support area plane, such as
RK3288 and RK3399, one group of area planes share same hardware,
reuse the hardware on different scanout time, this design is
useful to support mulit planes with low hardware consume.

The plane hardware is used when the display scanout run into plane active
scanout, that means we can reuse the plane hardware resources on plane
non-active scanout.
Because resource share, There are some limit on share plane: one group
of share planes need use same zpos, can't not overlap, etc.
We assume share plane is a universal plane with some limit flags.
people who use the share plane need know the limit, should call the ioctl
DRM_CLIENT_CAP_SHARE_PLANES, and judge the planes limit before use it.

Under some circumstances the Frame Composer arithmetic unit can miss
an FC register write due to being busy processing the previous one.
The issue can be worked around by issuing a TMDS software reset and
then write one of the FC registers several times. After tested, the
number of iterations of RK3399/RK3328(v2.11a), RK3368(v2.01a),
RK3288(v2.00a) is one.
