ARM: dts: sunxi: Add regulator-boot-on to usb host port regulator nodes

Browse Source 
u-boot will have turned on the power to the usb host ports, so mark them
as regulator-boot-on, this stops the power on the ports from temporarily
getting turned off during boot, causing issues with e.g. usb powered
harddisks.
