accel/ivpu: Clear specific interrupt status bits on C0



commit 7f34e01f upstream.

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.
