Move sequence of masking and unmasking global interrupts from buttress
interrupt handler to generic one that handles both VPUIP and BTRS
interrupts.

Unmasking global interrupts will re-trigger MSI for any pending interrupts.
Lack of this sequence can randomly cause to miss any VPUIP interrupt that
comes after reading VPU_40XX_HOST_SS_ICB_STATUS_0 and before clearing
all active interrupt sources.

Fixes: 79cdc56c4a54 ("accel/ivpu: Add initial support for VPU 4")
