wifi: mt76: connac2: add per-chip PCIe register definitions

Browse Source 
Add MT_PCIE_MAC_{INT_ENABLE,PM} definitions to mt7921/regs.h and
wire up mt7921_pcie_reg in mt7921_pci_probe() to provide connac2
series chips with their own PCIe register definitions.

This is a preparation patch before enabling MT7928 PCIe support.
