libpayload: usb: Make OHCI work with ARM systems

Hardware / Coreboot - Julius Werner [chromium.org] - 22 October 2014 16:53 UTC

This patch enables the OHCI driver to use DMA memory, which is necessary for ARM systems where DMA devices are not cache coherent. I really only need this to test some later OHCI changes, but it was easy enough... copied almost verbatim from ehci.c.
