Implement MSI support.
MSI are implemented via Inbound Shared Doorbell 1 interrupts. Interrupts
are triggered by writing to Software Triggered Interrupt registeri (PCIe
card using physical address of this register in BAR0 space). There are 32
interrupts available. It can be increased by using Doorbell 2 and
Doorbell 3 registers to 96 interrupts.
