usb: chipidea: add host role This adds EHCI host support to the chipidea driver. We want it to be part of the hdrc driver and not a standalone (sub-)driver module, as the structure of ehci-hcd.c suggests, so for chipidea controller we hack it to not provide platform-related code, but only the ehci hcd. The ehci-platform driver won't work for us here too, because the controller uses the same registers for both device and host mode and also otg-related bits, so it's not really possible to put ehci registers into a separate resource. This is not a pretty solution, but the alternative is exporting symbols from the chipidea driver to a ehci-chipidea driver and doing all the module refcounting.
