drm/amdgpu: fix gmc init fail in sriov mode

Browse source

"adev->gfx.rlc.rlcg_reg_access_supported = true;"
the above varible were set too late during driver initialization.
it will cause the driver to fail to write/read register during GMC hw init
in sriov mode.

move gfx_xxx_init_rlcg_reg_access_ctrl() function to gfx early init stage
to avoid this issue.

Fixes: 5d447e2967 ("drm/amdgpu: add helper for rlcg indirect reg access")
