usb: misc: add support for new OF onboard hub binding
The new binding allows describing hubs that lacks a control bus (e.g.
I2C) in the DT and thus replaces the ugly hack of specifying USB hub
resets as gpio-hogs. It's already in use for boards we support, like the
STM32MP13/5 Discovery kits and will be useful for the i.MX8MP Debix
board, so port over the driver from Linux.
