wpa_supplicant: Enable HT40 and VHT automatically when setting up AP mode operation

[Jose Blanquicet]

According to previous discussion, the idea is to automatically enable VHT
based on driver capabilities when setting up an AP mode operation. It
can be prevente by means of disable_vht parameter. Currently, it is not
even possible to enable VHT in AP mode.

In addition, TODO task to enable automatically HT40 was implemented
for AP mode. It can be prevented using disable_ht40.

Remaining TODO tasks:
	- Use HT40+ or HT40- based on Beacons detection.
	- Support 160MHz and 80+80MHz channel width

What do you think?
