wifi: rtw89: pci: add PCI generation struct to reuse common flow

For WiFi 7 chips, the PCI settings are similar, but registers' names are changed, so it will be difficult to understand the code if we mix the code of two generations into one function. Therefore, we add a struct to abstract PCI generation info, and put the code used by WiFi 7 chips in pci_be.c.

Then, the struct hierarchy looks like

rtwdev
|
v
const struct rtw89_pci_info *pci_info; // per chip (e.g. 8922ae.c)
|
v
const struct rtw89_pci_gen_def *gen_def; // per generation (e.g. pci_be.c)

Ping-Ke Shih (5):
wifi: rtw89: pci: add PCI generation information to pci_info for each
chip
wifi: rtw89: pci: use gen_def pointer to configure mac_{pre,post}_init
and clear PCI ring index
wifi: rtw89: pci: implement PCI mac_pre_init for WiFi 7 chips
wifi: rtw89: pci: add LTR v2 for WiFi 7 chip
wifi: rtw89: pci: implement PCI mac_post_init for WiFi 7 chips
