commit dbd1003d1252db5973dddf20b24bb0106ac52aa2 upstream.

There is problem with 3DCGCG firmware and it will cause compute test
hang on picasso/raven1. It needs to disable 3DCGCG in driver to avoid
compute hang.

Use generic PCI reset for GPU reset if the user specifies
PCI reset as the reset mechanism.  This should in general
only be used for validation.

<content type='text'>
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.

Switch to smuio callbacks: use smuio v9_0 callbacks
for Vega10/12, smuio v11_0 callbacks for Vega20/Arcturus.
APUs don't support enable/disable rom clock gating and
also don't support read bios from rom. So APU flag check
is needed in clock gating callbacks and asic funciton
for read bios from rom to prevent access unknown offset
on APU.
