hostapd: update mesh DFS patches and add mesh HE support

Drop outdated and by now broken patchset originally supplied by
Peter Oh in August 2018 but never merged upstream.
Instead add the more promissing rework recently submitted by
Markus Theil who picked up Peter's patchset, fixed and completed it
and added support for HE (802.11ax) in mesh mode.

This is only compile tested and needs some real-life testing.

Fixes: FS#3214
Fixes: 167028b750 ("hostapd: Update to version 2.9 (2019-08-08)")
Fixes: 0a3ec87a66 ("hostapd: update to latest Git hostap_2_9-1238-gdd2daf0848ed")
Fixes: 017320ead3 ("hostapd: bring back mesh patches")

+Subject: [PATCH 09/19] mesh: update ssid->frequency as pri/sec channel switch
+
+ssid->frequency is one of variables used to gets channel
+number from given frequency. Leave it as unchanged when
+pri/sec channel switched will cause picking up wrong
+channel number after applying secondary channel offset
+for HT40 and leads failing interface bring-up.
