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*
