autotests: Update the wiphy_map and hostapd_map structs

In the test utilties updated the wiphy_map struct built from the
TEST_WIPHY_LIST variable to parse the new format and to use a new
structure where each wiphy is a namedtuple and each interface under it
also contains a reference to that wiphy.  The 'use' field is now
assigned to the wiphy instead of to the interface.
