PCI: thunder-pem: Add support for cn81xx and cn83xx SoCs
The pci-thunder-pem driver was initially developed for cn88xx SoCs. The cn81xx and cn83xx members of the same family of SoCs have a slightly different configuration of interrupt resources in the PEM hardware, which prevents the INTA legacy interrupt source from functioning with the current driver. There are two fixes required: 1) Don't fixup the PME interrupt on the newer SoCs as it already has the proper value. 2) Report MSI-X Capability Table Size of 2 for the newer SoCs, so the core MSI-X code doesn't inadvertently clobber the INTA machinery that happens to reside immediately following the table.
