Subject: [PATCH AUTOSEL 5.0 06/67] mips: bcm47xx: Enable USB power on Netgear WNDR3400v2

From: Petr Štetiar <ynezz@...e.cz>

[ Upstream commit cdb8faa00e3fcdd0ad10add743516d616dc7d38e ]

Eric has reported on OpenWrt's bug tracking system[1], that he's not
able to use USB devices on his WNDR3400v2 device after the boot, until
he turns on GPIO #21 manually through sysfs.
