accel/ivpu: Clear specific interrupt status bits on C0
MTL C0 stepping fixed issue related to butrress interrupt status clearing,
to clear an interrupt status it is required to write 1 to specific
status bit field. This allows to execute read, modify and write routine.
Writing 0 will not clear the interrupt and will cause interrupt storm.
