Provide the methods to let ACPI identify the need to use xhci-platform. Change the Kconfig files so the xhci-plat.o file is selectable during kernel config. This has been tested on an ARM64 machine with platform XHCI, an x86_64 machine with XHCI, and an x86_64 machine without XHCI. There were no regressions or error messages on the machines without platform XHCI.

You shoudn't need this #ifdef, right? thanks, greg k-h
