Subject: drm/amd/display: fix build error on arm64
Git-commit: eff4ccd11313ecc8ec94c0f39961ffbf227a406d
Patch-mainline: v6.1-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225 jsc#PED-2849
dcn20_build_mapped_resource() and dcn20_acquire_dsc() is not defined,
if CONFIG_DRM_AMD_DC_DCN is disabled.
Fix the following build error on arm64:
ERROR: modpost: "dcn20_build_mapped_resource" [drivers/gpu/drm/amd/amdgpu/amdgpu.ko] undefined!
ERROR: modpost: "dcn20_acquire_dsc" [drivers/gpu/drm/amd/amdgpu/amdgpu.ko] undefined!
Fixes: 20dad3813b3c ("drm/amd/display: Add a helper to map ODM/MPC/Multi-Plane resources")
