cover rtw89: handle TX power limit of 6G and 160M

Add TX power limit of 6G and 160M support to framework, so the new chip can work based on this.

PATCH 1/2 rtw89: phy: handle txpwr lmt/lmt_ru of 6G band

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

Add declarations of 6G stuff and extend rtw89_channel_to_idx() to map 6G's channels to 6G channel indexes. While 6G, correspondingly read 6G's entry for tx power limit and limit_ru.

After this, we should pay attention to chip_info::support_bands. If a chip declares 6G support, it must configure txpwr_lmt_6g and txpwr_lmt_ru_6g in case accessing NULL pointer while setting tx power limit/limit_ru on 6G band.
