scsi: pm80xx: Mask and unmask upper interrupt vectors 32-63

[ Upstream commit 294080eacf92a0781e6d43663448a55001ec8c64 ]

When upper inbound and outbound queues 32-63 are enabled, we see upper
vectors 32-63 in interrupt service routine. We need corresponding registers
to handle masking and unmasking of these upper interrupts.

To achieve this, we use registers MSGU_ODMR_U(0x34) to mask and
MSGU_ODMR_CLR_U(0x3C) to unmask the interrupts. In these registers bit 0-31
represents interrupt vectors 32-63.
