From: Zong-Zhe Yang <kevin_yang@xxxxxxxxxxx>
DPK is one kind of RF calibration. When MCC (multi-channel concurrency)
start/stop, DPK needs to do extra things to be off/on. We add a chanctx
callback type, RTW89_CHANCTX_CALLBACK_RFK, and register it for RTL8852C
to deal with DPK according to MCC states.
