USB: ehci-omap: Tweak PHY initialization sequence
commit 4e5c9e6fa2d232a0686d5fe45cd1508484048936 upstream.
For PHY mode, the PHYs must be brought out of reset
before the EHCI controller is started.
This patch fixes the issue where USB devices are not found
on Beagleboard/Beagle-xm if USB has been started previously
by the bootloader. (e.g. by "usb start" command in u-boot)
Tested on Beagleboard, Beagleboard-xm and Pandaboard.
Issue present on 3.10 onwards.
