accel/ivpu/37xx: Fix missing VPUIP interrupts
commit b132ac51d7a50c37683be56c96ff64f8c887930f upstream.
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 will cause the driver to miss any
VPUIP interrupt that comes after reading VPU_37XX_HOST_SS_ICB_STATUS_0
and before clearing all active interrupt sources.
Fixes: 35b137630f08 ("accel/ivpu: Introduce a new DRM driver for Intel VPU")
