wifi-scripts: mac80211.sh: add EHT and HE160 support to iw_htmode
For WIFI7 devices (such as mt7925e), the dev width is currently
always "20 MHz (no HT)" in monitor mode.
Add EHT and HE160 support to iw_htmode to fix this issue.
Additionally, the following changes are made:
1. Set iw_htmode to 160MHz for VHT160. The reason for the current
VHT160 setting is unclear and seems to have been in place for
over a decade (ibss_htmode [1]). If anyone knows its impact,
please inform me so I can restore it.
2. Modify MHZ to MHz. The original matching table in the current
iw tool uses MHz. Although the match is case-insensitive,
correcting this won't hurt.
