drm/amdgpu: Move CAP firmware loading to the beginning of PSP firmware list

[Why]
As PSP needs to verify the signature, CAP firmware must be loaded first when PSP loads firmwares.
Otherwise, when DFC feature is enabled, CP firmwares would be loaded failed.

[ 1149.160480] [drm] MM table gpu addr = 0x800022f000, cpu addr = 00000000a62afcea.
[ 1149.209874] [drm] failed to load ucode CP_CE(0x8)

[How]
Move CAP UCODE ID to the beginning of AMDGPU_UCODE_ID enum list.
