[PATCH 06/20] wifi: mt76: connac2: add per-chip PCIe register definitions

[JB Tsai <jb.tsai@mediatek.com>]

From: Emery Hsin <emery.hsin@mediatek.com>

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.
