wifi: rtw89: ps: refactor channel info to firmware before entering PS

In PS mode, firmware needs hardware parameters related to channel info
to configure hardware itself. Before entering PS, driver prepares these
info to firmware via firmware H2C command.

Since firmware only consider PS for single one vif, change the argument
of entry function to rtwvif, and only consider first link for this old
H2C command that only support legacy.
