Subject: [PATCH V4 5/5] usb: host: Add ability to build new Broadcom STB USB drivers
Add the build system changes needed to get the Broadcom STB XHCI,
EHCI and OHCI functionality working. 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.
