patches/openwrt: rpcd: backport 802.11ax support
Thís is required to detect ax modes and more HT modes for mini PCIe Wi-Fi card: MT7915E 802.11ax PCI Express Wireless Network Adapter
It can be reproduced before and after this commit by using following comands:
a) iwinfo device htmodelist
b) ubus call iwinfo info '{"device":"radio2"}'
Because Foris Controller detects Wi-Fi cards by using ubus (iwinfo info...), so they don't need to parse output from iwinfo or details from /sys
Tested on Turris Omnia, OpenWrt 21.02, mvebu/cortex-a9
