drm/amd/display: Fix annotations for dc state functions

This patch addresses inconsistencies in the annotations for the
following functions:

- **dc_get_power_profile_for_dc_state**: Standardized parameter and
  return value annotations.
- **dc_get_det_buffer_size_from_state**: Clarified parameter
  documentation for better understanding.
- **dc_get_host_router_index**: Corrected parameter descriptions to
  follow documentation conventions.

Fixes the below:
drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc.c:6386: warning: Cannot understand  ***************
