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Drop outdated and by now broken patchset originally supplied by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 04/19] wpa_supplicant: fix frequency config for non p2p vht/he
+ cases
+
+Fix compile without CONFIG_P2P and only set secondary channel seg idx
+if we use a mode supporting a sec channel for vht/he.
