e6fac6a9c9 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)
[ 1149.209878] [drm] psp gfx command LOAD_IP_FW(0x6) failed and response status is (0xFFFF0007)
[ 1149.215914] [drm] failed to load ucode CP_PFP(0x9)
[ 1149.215917] [drm] psp gfx command LOAD_IP_FW(0x6) failed and response status is (0xFFFF0007)
[ 1149.221941] [drm] failed to load ucode CP_ME(0xA)
[ 1149.221944] [drm] psp gfx command LOAD_IP_FW(0x6) failed and response status is (0xFFFF0007)

[ 1149.242382] [drm] psp gfx command LOAD_IP_FW(0x6) failed and response status is (0xFFFF0007)

[How]

c4381d0ee8 drm/amdgpu: Add interface to load SRIOV cap FW
- Add interface to load SRIOV cap FW. If the FW does not
  exist, simply skip this FW loading routine.
  This FW will only be loaded under SRIOV. Other driver
  configuration will not be affected.
  By adding this interface, it will make us easier to
  prepare SRIOV Linux guest driver for different users.

- Update sysfs interface to read cap FW version.

- Refactor PSP FW loading routine under SRIOV to use a
  unified SWITCH statement instead of using IF statement

- Remove redundant amdgpu_sriov_vf() check in FW loading
  routine

0753e56e9a drm/amdgpu: correct RLC firmwares loading sequence
Per confirmation with RLC firmware team, the RLC should
be unhalted after all RLC related firmwares uploaded.
However, in fact the RLC is unhalted immediately after
RLCG firmware uploaded. And that may causes unexpected
PSP hang on loading the succeeding RLC save restore
list related firmwares.
So, we correct the firmware loading sequence to load
RLC save restore list related firmwares before RLCG
ucode. That will help to get around this issue.

Including amdgpu_ucode.h directly will cause warnings, since amdgpu.h is
