From: Zong-Zhe Yang <kevin_yang@xxxxxxxxxxx>
Wi-Fi 6 chips and Wi-Fi 7 chips have different register design for
TX power limit. We rename original setting stuffs with a suffix `_ax`,
concentrate related enum declaration in phy.h, and implement setting
flow for Wi-Fi 7 chips. Then, we set TX power limit according to chip
generation.
