AP: Add 40 MHz channel bandwidth capability support for 2.4 GHz band

This change extends the earlier 40 MHz support in hostapd.conf for 5 GHz
band to 2.4 GHz band APs with the help of a new parameter option
"2.4_HT40" in the "-r" command-line argument.

Also update default_ap_chwidth variable name with
default_11na_ap_chwidth to refer to 5 GHz.
