Port ehci-omap from .32

In order to fix modem with a dirty hack, use ehci-omap
from 2.6.32.

There are still some things missing (like the right references
for memcpy).

ehci_hcd_omap_mode (2.6) became usbhs_omap_port_mode (3.0)
usbhs_omap_board_data (3.0) still misses some parts from
ehci_hcd_omap_port_data (2.6).

Oh and yes it doesn't boot at all...
