commit 75ee07b03fc6ec0a7ac7407f9ea7b3e981efb28f
Author: Zong-Zhe Yang <kevin_yang@realtek.com>

wifi: rtw89: link rtw89_vif and chanctx stuffs
First, introduce struct rtw89_sub_entity for chanctx related stuffs.
Second, add enum rtw89_sub_entity_idx to rtw89_vif for vif operation
to access its/right chanctx stuffs after future multi-channel support.
Besides, RTW89_SUB_ENTITY_0 is the default chanctx entry throughout
driver, i.e. it's used for things which may not have a target chanctx
yet. So, we need to ensure that RTW89_SUB_ENTITY_0 is always working.
If there is at least one alive chanctx, then one of them must take
RTW89_SUB_ENTITY_0. If no alive chanctx, RTW89_SUB_ENTITY_0 will be
filled by rtw89_config_default_chandef().
