msm: mdss: fix clearing interrupts of DSI0 during isr for DSI1



Currently we need to handle DSI-1 interrupts only for panel/DCS
commands in the software during broadcast mode. When we handle
isr for DSI-1 interrupt, we clear all the interrupts for DSI-0
also. This might cause timeout issues for waits on DSI-0
interrupts like CMD_MDP_DONE since the interrupt is cleared
and we do not handle the interrupt for DSI-0. Fix this issue
by clearing only the DMA_DONE interrupt for DSI-0 during the
isr handling for DSI-1.
