[PATCH 67/89] drm/amd/pm: disable manually setting MCLK power level on yellow carp

From: Xiaomeng Hou <Xiaomeng.Hou at amd.com>

PMFW provides specific messages for setting fclk freq range thus adjust
the power level. There's misusing of these messages when setting
dpm mclk. Since actually mclk could adjust automatically complying with
fclk, remove standalone support for mclk dpm level setting.
