[PATCH v3 13/18] rtw89: 8852a: add 8852a specific files

[Ping-Ke Shih <pkshih@realtek.com>]

The 8852A specific chip info and ops are written in this file. The chip
info describes the chip specific capabilities, and chip ops are specific
efuse parser, FEM setup, set channel, RFK trigger, set TX power, and
WL/BT grant controlled by coex.
