wenlong.zhang d30cc6178f drm: add rdma table for drm osd registers [1/1] ...

PD#SWPL-101847

Problem:
drm write registers to rdma table one by one, due to rdma table update
and rdma manager flush to real register are out of sync, so we want to
creat a fake table, the fake table will copy to rdma table after
pipeline register write done, and then config rdma vsync

Solution:
add rdma table for drm osd registers, and it can dynamic switching by
this node /sys/class/drm/card0/crtc0/rdma_table_switch.
echo 1 > /sys/class/drm/card0/crtc0/rdma_table_switch switch off
echo 0 > /sys/class/drm/card0/crtc0/rdma_table_switch switch on

Verify:
T3x s7 s5

Test:
DRM-OSD-33
