Add QCA_NL80211_VENDOR_SUBCMD_MCC_QUOTA. When two or more interfaces are
active on the same band and two different home channels (MCC), the
target may allocate quota of "on channel" time for each home channel.
The target will indicate the quota information to application layer with
this event. Application may do TX bitrate control based on the
information. The user may also set the MCC quota for an interface by
using this command.
