usb: host: Add ability to build new Broadcom STB USB drivers

Browse Source 
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. Also update MAINTAINERS.

Enables support for XHCI, EHCI and OHCI host controllers
found in Broadcom STB SoC's.
To compile these drivers as modules, choose M here: the
modules will be called ohci-platform.ko, ehci-brcm.ko and
xhci-plat-hcd.ko
Disabling this will keep the controllers and corresponding
PHYs powered down.
