Subject: [PATCH 5/5] drm/amdgpu: disable rom clock gating support for APUs

ROM clock gating enable/disable is not supported on APU platform. (i.e. CGTT_ROM_CLK_CTRL0 register is not availabe on APU). SMUIO callbacks will check APU flag before enable/disable rom clock gating, and skip the programming. Accordingly, query clock gating status through CGTT_ROM_CLK_CTRL0 also doesn't support on APU platform.

The change applies to RAVEN/RAVEN2/PICASSO/RENOIR.
