Add the build system changes needed to get the Broadcom STB XHCI, EHCI and OHCI functionality working. 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.
