disp: msm: sde: reset crop registers in PU cases

Browse Source 
In back to back partial update cases with CWB the CROP
registers are not reset causing WB timeout in the
following sequence-
1) Nth commit WB_roi != LM_PU_roi, WB CROP registers
are programmed.
2) N+1th commit WB_roi == LM_PU_roi, WB CROP registers
are not cleared retaining old values.
Clear the WB CROP registers in the second case to fix
the issue.
