[PATCH] usb: renesas_usbhs: make usbhs_write32() static

[ben.dooks@codethink.co.uk (Ben Dooks)]

The usbhs_write32 function is not used outside of the rcar3.c
file, so fix the following sparse warning by making it static:

drivers/usb/renesas_usbhs/rcar3.c:26:6: warning: symbol 'usbhs_write32' was not declared. Should it be static?
