OMAP5: EHCI: Add ehci port support for omap5 evm
On omap5 board port2 is connected to smsc4640 hub having two
downstream ports and port3 is connected to SMSC LAN9730 controller
so add the port2/3 support and both controllers need gpio reset,
update uhh_pdata with appropriate gpio numbers. Currently ehci
module limits gpio reset only to two ports hence add port3 gpio reset
which will be used in omap5 board by ethernet chip.
Both port3 and port2 are configured in hsic mode as per external
smsc controllers requirements.
