S3 support on some GFX11 products

[AMD Official Use Only - General]

Hi,

Some GFX11 based products will have S3 support as an option, but to support this some of the suspend flow had to be adjusted in kernel 6.4 for it to work properly.

For 6.2.y/6.3.y the following commit is needed: f7f28f268b86 ("drm/amd/pm: re-enable the gfx imu when smu resume")

For 6.1.y the following two commits are needed: 484d7dcc709d ("swsmu/amdgpu_smu: Fix the wrong if-condition") f7f28f268b86 ("drm/amd/pm: re-enable the gfx imu when smu resume")

Can you please backport them?

Thanks,
