drm/i915/icl: update ddb entry start/end mask during hw ddb readout
Gen11/ICL onward ddb entry start/end mask is increased from 10 bits to
11 bits. This patch make changes to use proper mask for ICL+ during
hardware ddb value readout.
Changes since V1:
- Use _MASK & _SHIFT macro (James)
Changes since V2:
- use kernel type u8 instead of uint8_t
Changes since V3:
- Rebase
