phy-rcar-usb: correct base address
The memory region that is used by the driver overlaps EHCI and OHCI register
regions for absolutely no reason now -- fix it by adding offset of 0x800 to
the base address, changing the register #define's accordingly. This has extra
positive effect that we now can use devm_ioremap_resource()...
Note that the driver and the SoC code have to be in one patch to keep the code
bisectable...
The patch has been tested on the Marzen board.
