radv: fix another case of VRS with mipmaps on GFX10.3

Browse source 
When a VRS view is used with a depth/stencil view, the driver is
expected to copy the VRS rates to the HTILE buffer of the depth/stencil
view. Though if the image uses mipmaps and the base level can't support
HTILE there is no way to copy the rates. The workaround is to force VRS
to be 1x1 which is valid in Vulkan.

This fixes old VKCTS failures on RAPHAEL just because it supports
fragmentShadingRateWithShaderDepthStencilWrites compared to other GPUs
in CI (NAVI21/VANGOGH).
