kernel: fix usb chipidea controller support
If ehci platform driver is loaded before the chipidea controller driver, both are competing for the same IO resources and the generic driver gets used for the hardware. This results in USB device mode being unavailable. Split generic EHCI support code out of kmod-usb2, so that the chipidea driver can be included without also pulling in the generic one. Also rework the load order, so that the chipidea driver gets loaded first, in case both are installed Signed-off-by: Felix Fietkau <nbd@nbd.name>
