wlan: SAPHT40 2.4GHz: Add new message type for setting HT20/40 mode

To update the SAP/P2P GO from HT20 to HT40 or viceversa,
a new message type for setting HT20/40 mode of SAP/P2P GO
is added. When SAP/P2P GO HT20/40 mode is changed, a message
is sent to Lim in order to change the beacon content accordingly.
