[PATCH 1/3] drm/amdgpu/pm: add capped/uncapped power profile modes

[Perry Yuan]

Capped and uncapped workload types switching are supported on Vangogh,
User can switch the power profile and check current type with below commands.

1) switch to capped mode:
`# echo 8 > /sys/class/drm/card0/device/pp_power_profile_mode`

2) switch to uncapped mode:
`# echo 9 > /sys/class/drm/card0/device/pp_power_profile_mode`

3) check current mode:
$ cat /sys/class/drm/card0/device/pp_power_profile_mode
 1 3D_FULL_SCREEN
 3          VIDEO
 4             VR
 5        COMPUTE
 6         CUSTOM
 8         CAPPED
 9       UNCAPPED*
