hostapd(hidl): Implementation of HIDL methods

The core functions invoked in these HIDL methods are equivalent to
the socket interface command implementations (ctrl_iface.c).
a) addAccessPoint - Equivalent to |ADD| & |ENABLE| commands in the
socket interface.
b) removeAccessPoint - Equivalent to |REMOVE| command in socket
interface.
