596b6f51b71eb1dd6f603b3f5aeb0a2f9300b21f cadence_gem: Correct the interupt logic
This patch fixes two mistakes in the interrupt logic.
First we only trigger single-queue or multi-queue interrupts if the status
register is set. This logic was already used for non multi-queue interrupts
but it also applies to multi-queue interrupts.
Secondly we need to lower the interrupts if the ISR isn't set. As part
of this we can remove the other interrupt lowering logic and consolidate
it inside gem_update_int_status().
