Since the drm atomic framework, only a small part of the vop
register needs sync write, Currently seems only following registers
need sync write:
    cfg_done, standby and interrupt related register.

All ctrl registers are using the sync write method that is
inefficient, hardcode the write_relaxed flags to vop registers,
then can only do synchronize write for those actual needed register.
