drm/msm/sde: increase timeout period for CTL_RESET before panic

Currently CTL_RESET timeout is 2ms. In certain smmu fault cases
due to external subsystem like camera, the CTL_RESET timeout panic
is hit before smmu error is reported as fatal error. Increasing the
timeout period to 100 ms so that original issue of smmu errors can be
debugged and not report false display issue.
