Subject: drm/msm/dpu: simplify DPU_SSPP features checks
Git-commit: 1e35e3fc3f714045078a6b4fcb4f0fe61df9e328
Patch-mainline: v5.17-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

Add DPU_SSPP_CSC_ANY denoting any CSC block. As we are at it, rewrite
DPU_SSPP_SCALER (any scaler) to use BIT(x) instead of hand-coded
bitshifts.
