Felix Fietkau 847984c773 hostapd: reimplement AP/STA support via ucode
Drop obsolete control interface patches.
This fixes some corner cases in the previous code where the segment 0 center
frequency was not adjusted properly, leading to logspam and non-working AP
interfaces.
Additionally, shutting down the AP was broken, because the next beacon update
would re-enable it, leading to a race condition on assoc.
