Subject: drm/amd/display: fix undefined struct member reference
Git-commit: 1f00534a764aed160652770e0c0a63657c231fde
Patch-mainline: v5.5-rc2
References: bsc#1152472

An initialization was added for two optional struct members.  One of
these is always present in the dcn20_resource file, but the other one
depends on CONFIG_DRM_AMD_DC_DSC_SUPPORT and causes a build failure if
that is missing:

drivers/gpu/drm/amd/amdgpu/../display/dc/dcn20/dcn20_resource.c:926:14: error: excess elements in struct initializer [-Werror]
   .num_dsc = 5,

Add another #ifdef around the assignment.

Fixes: c3d03c5a196f ("drm/amd/display: Include num_vmid and num_dsc within NV14's resource caps")
