ehci: fix port connect status programming

Current programming takes the default vaule of HSUSB port status
from UHH_HOSTCONFIG and write back the same to UHH_HOSTCONFIG
without updating.

This patch updates the port status based on board configuration.

Without this patch EHCI port becomes unusable on OMAP3EVM when a
USB HDD is connected to it through a HS HUB and we get below
error message,

"hub 1-0:1.0: Cannot enable port 1.  Maybe the USB cable is bad?"
