Hans de Goede c9f8947e66 sunxi: usb-phy: Never power off the usb ports
USB devices are not really designed to get the power bounced off and on
at them. Esp. USB powered harddisks do not like this.

Currently we power off the USB ports both on a "usb reset" and when
booting the kernel, causing the usb-power to bounce off and then back
on again.

This patch removes the powering off calls, fixing the undesirable power
bouncing.

Note this requires some special handling for the OTG port:
1) We must skip the external vbus check if we've already enabled our own
vbus to avoid false positives
2) If on an usb reset we no longer detect that the id-pin is grounded, turn
off vbus as that means an external vbus may be present now
