drm/amdgpu: extend profiling mode.
in profiling mode, powerplay will fix power state
as stable as possible.and disable gfx cg and LBPW feature.
profile_standard: as a prerequisite, ensure power and thermal
sustainable, set clocks ratio as close to the highest clock
ratio as possible.
profile_min_sclk: fix mclk as profile_normal, set lowest sclk
profile_min_mclk: fix sclk as profile_normal, set lowest mclk
profile_peak: set highest sclk and mclk, power and thermal not
sustainable
profile_exit: exit profile mode. enable gfx cg/lbpw feature.
