lantiq: fritz7320: enable USB power supply
The USB ports if a FRIZZ!Box 7320 do not supply power to connected devices. Add the GPIOs enabling USB power as regulator, to enable USB power supply as soon as the USB driver is loaded. Fixes FS#3624 Signed-off-by: Mathias Kresin <dev@kresin.me> (cherry picked from commit 6e4e97b2256327bb380ee2a83da9a1ddf657e395)
