mac80211: separate encoding/bandwidth from flags

We currently use a lot of flags that are mutually incompatible,
separate this out into actual encoding and bandwidth enum values.

Much of this again done with spatch, with manual post-editing,
mostly to add the switch statements and get rid of the conversions.
