Dhaval Patel 31d4bb10a6 disp: msm: sde: add xin client clock status for wb2
CWB may trigger frame missed message if interrupts
are disabled on specific CPU. WB2 will only find single
interrupt status for two posted start triggered frame.
SDE driver will start checking the xin client clock
status for wb2 timeout case to trigger the valid
frame done status.
