Subject: [PATCH 4/7] wifi: rtw89: phy: set TX power limit according to chip gen

From: Zong-Zhe Yang <[email protected]>

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.
