drm/amd/display: Create debug option to disable v.active clock change policy.
[WHY]
It has been a useful option in debugging GFXOFF and P.State Change issues.
May be required as for platform specific workaround.
[HOW]
Create option in enum dc_debug_options, "disable_vactive_clock_change".
When it is set, dm_dram_clock_change_vactive, will translate into
p_state_change_support: false.
