hostapd: fix encrypted mesh channel settings
Import two patches from Peter Oh to allow setting channel
bandwidth in the way it already works for managed interfaces.
This fixes mesh interfaces on 802.11ac devices always coming up in
VHT80 mode.
Add a patch to allow HT40 also on 2.4GHz if noscan option is set, which
also skips secondary channel scan just like noscan works in AP mode.
This time also make sure to add all files to the patch before
committing it...

+Subject: [PATCH 1/2] mesh: add VHT_CHANWIDTH_USE_HT to max_oper_chwidth
+
+Channel width in VHT mode refers HT capability when
+the width goes down to below 80MHz, hence add checking
+HT channel width to its max operation channel width.
+So that mesh has capable to select bandwidth below 80Mhz.

+Subject: [PATCH 2/2] mesh: implement use of VHT20 config in mesh mode
+
+mesh in VHT mode is supposed to be able to use any bandwidth
+that 11ac supports, but we don't have a way to set VHT20
+although there are parameters that are supposed to be used.
+This patch along with the patch of
+"mesh: add VHT_CHANWIDTH_USE_HT to max_oper_chwidth" makes mesh
+available to use of any bandwidth using combination of
+existing parameters like below shown.
+
+VHT80:
+ default
+ do not set any parameters
+VHT40:
+ max_oper_chwidth = 0
+VHT20:
+ max_oper_chwidth=0
+ disable_ht40=1
+HT40:
+ disable_vht = 1
+HT20:
+ disable_ht40 = 1
+disable HT:
+ disable_ht = 1
