ARM: rmobile: Move HSUSB configuration to board on ULCB

In order to use ehci-generic driver, move the configuration of HSUSB
block into the board file. This configuration should not have been in
the Gen3 EHCI USB driver in the first place, so move it to the board
file until there is a proper infrastructure and driver for the HSUSB
block.
