drm/amdgpu: Add PSP loading support for DMCUB ucode

Browse Source 
DMCUB ucode requires secure loading through PSP. This is already
supported in PSP as GFX_FW_TYPE_DMUB, it just needs to be mapped from
AMDGPU_UCODE_ID_DMCUB to GFX_FW_TYPE_DMUB.

DMUB is a shorthand name for DMCUB and can be used interchangeably.
