[PATCH] drm/amdgpu/pm: Don't show pp_power_profile_mode for YC and later APUs

[Mario Limonciello]

This command corresponding to this attribute was deprecated in the PMFW
for YC so don't show a non-functional attribute.

Since future APUs may be brought up using IP version checking also
disable it for future APU's.  If any do support the command then they
can be treated as exceptions.
