Subject: drm/amd/display: Cache cursor when cursor exceeds 64x64
Git-commit: 4074f96d0f2db2fcbd8e223aebe60ca445b8aeae
Patch-mainline: v6.0-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
[Why]
When Static screen from MALL, the cursor needs to be
cached if cursor exceeds 64x64 size.
[How]
Program the bit that cache cursor in MALL when size
of the cursor exceeds 64x64.
