[PATCH v2 1/2] wifi: mac80211: add EHT MU-MIMO related flags in ieee80211_bss_conf

[Ryder Lee]

Similar to VHT/HE. This is utilized to pass MU-MIMO configurations
from user space (i.e. hostapd) to driver.

changes since v2 
- fix typo of commit logs.
- revise statement of newly added members in ieee80211_bss_conf
- remove unneeded braces.
