wiphy: add getter for frequency/band info 

This adds two new APIs:

wiphy_get_frequency_info(): Used to get information about a given
frequency such as disabled/no-IR. This can also be used to check
if the frequency is supported (NULL return is unsupported).

wiphy_band_is_disabled(): Checks if a band is disabled. Note that
an unsupported band will also return true. Checking support should
be done with wiphy_get_supported_bands()
