The OHCI support does not require anything unique to Broadcom so the standard ohci-platform driver is being used. The link order for XHCI was changed in the Makefile because of the way STB XHCI, EHCI and OHCI controllers share a port which requires that the XHCI driver be initialized first. Also update MAINTAINERS.
