msm: display: Handle display shutdown properly for 8x25

When continuous splash scren is enabled, the MDP and MIPI DSI
interrupts are not getting disabled during display shutdown
sequence. This is causing huge number of interrupts getting fired
during display init on kernel side causing the target to not boot
up sometimes. Handle display shutdown during bootloader exit
properly.
