Kconfig: Extract CONFIG_USB_CHIPIDEA from CONFIG_IMX

TYPE_CHIPIDEA models an IP block which is also used in TYPE_ZYNQ_MACHINE which
itself is not an IMX device. CONFIG_ZYNQ selects CONFIG_USB_EHCI_SYSBUS while
TYPE_CHIPIDEA is a separate compilation unit, so only works by accident if
CONFIG_IMX is given. Fix that by extracting CONFIG_USB_CHIPIDEA from CONFIG_IMX.
