disp: msm: dp: remove debug log output in isr 



Remove all debug logs and replace them with event logs in the isr
path. This change will reduce the likelihood of an interrupt storm
causing a watchdog bark if display threads are being prevented
from completing execution due to debug logs holding the console
lock.
