[PATCH] drm/amd/display: fix kernel-doc warnings for cgs register typedefs

[Omokefe Emmanuel Onanaroghene <emmaonana18@gmail.com>]

kernel-doc reports prototype mismatches for the cgs register accessor
typedefs, whose comments do not use the documented typedef format, e.g.:

  drivers/gpu/drm/amd/include/cgs_common.h:89 ... expecting prototype
  for cgs_read_register(). Prototype was for uint32_t() instead

Use the typedef comment format for all four accessors (also restoring
the dropped _t suffix) and replace the wrong @offset with the real
@space/@index params in the two indirect-register comments.
