From: Zong-Zhe Yang <kevin_yang@xxxxxxxxxxx>
After supporting more than one channel, we need entity mode to decide
how to set current channel(s) on the sub-entities. This decision may
happen on set_channel() and rtw89_core_set_chip_txpwr().
For now, we support single one channel and use only first HW entry,
i.e. RTW89_SUB_ENTITY_0, RTW89_MAC_0, RTW89_PHY_0. Without something
unexpected, the entity mode should always be RTW89_ENT_MODE_SCC after
recalcated, where SCC means single channel concurrency. So, an assert
is added in set_channel() and rtw89_core_set_chip_txpwr().
