[Intel-gfx] [PATCH 28/56] drm/i915/adl_p: Extend PLANE_WM bits for blocks & lines

ADL-P further extends the bits in PLANE_WM that represent blocks and
lines; we need to extend our masks accordingly. Since these bits are
reserved and MBZ on earlier platforms, it's safe to use the larger
bitmask on all platforms.
Bspec: 50419
