    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.
