Subject: [PATCH] wiphy: remove disabled_freqs and related dump code

The disabled_freqs list is being removed and replaced with a new
list in the band object. This completely removes the need for
the pending_freqs list as well since any regdom related dumps
can just overwrite the existing frequency list.
