MIPS: Netlogic: Add MSI support for XLP
Add MSI chip and MSIX chip definitions.
For MSI, we map the link interrupt to a MSI link IRQ which will
do a second level of dispatch based on the MSI status register.
The MSI chip definitions use the MSI enable register to enable
and disable the MSI irqs.
For MSI-X, we split the 32 available MSI-X vectors across the
four PCIe links (8 each). These PIC interrupts generate an IRQ
per link which uses a second level dispatch as well.
The MSI-X chip definition uses the standard functions to enable
and disable interrupts.
