Douglas Teles 492a61eee2 wifi: free the USB OTG port when WiFi is off (internal-WiFi mux boards) ...

Some clones (XiFan R36Max2 family) wire the internal USB WiFi module to
the same OTG data lines as the physical USB port through a hardware mux
gpio: WiFi and the port are mutually exclusive, and users report that on
the stock OS disabling WiFi brings the port back.

Port ROCKNIX's 0026 USB2 PHY patch, which reads switch-gpios from the
otg-port node and exposes usb_switch_gpio / usb_switch_ext in sysfs
(boot default: internal WiFi). ROCKNIX itself never toggles the mux from
userspace, so the physical port stays dead there; wire it to our WiFi
toggle instead: wifictl enable routes the mux to the internal module,
wifictl disable flips it to the external port and powers its vbus. The
sysfs writes are no-ops on boards without the mux, and the patch is
inert unless the generated overlay (USBMUX hardware variant on the site)
adds switch-gpios to the PHY.
