[5/5] arm: shmobile: koelsch: Add internal PCI support

Commit Message

Valentine Barshak Dec. 20, 2013, 2:14 p.m. UTC

This adds internal PCI USB host devices to R-Car M2 Koelsch board.
If USBHS device is disabled, channel 0 is configured as PCI USB host.
Otherwise, it is configured as USBHS. The USB phy is bound bound to
either USB host or USBHS device respectively.
