after modify, rockchip_dfi_ops can apply to other platform use such
version ddr monitor. regardless of channel count, only one channel
of rk3288,rk3399,rk3328 can work. and regardless of monitor clk,
some platform like rk3328 monitor clk is always on.

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.
