From: Zong-Zhe Yang <[email protected]>
Wi-Fi 6 chips and Wi-Fi 7 chips have different register design for TX
power RU 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 RU limit according to
chip generation.
