Add Pawel.

Hi Pawel,

Add old cdns3 logic, when the CONFIG_USB=m
If CONFIG_USB_CDNS3 is M, the host will be built as module
If CONFIG_USB_CDNS3 is build-in, the host will not built due to
USB=m, so USB!= USB_CDNS3 at below dependency.

config USB_CDNS3_HOST
	bool "Cadence USB3 host controller"
	depends on USB=y || USB=USB_CDNS3

So, it has no such issue.

But after adding CDNSSP support, the configuration relationship is
much complicated, both CDNS3 and CDNSSP could choose host file,
would you have a check for this issue?
