Subject: [PATCH] usb: chipidea: fix the build error with randconfig
Using below configs, the compile will have error:
ERROR: "ehci_init_driver" undefined!
.config:
CONFIG_USB_CHIPIDEA=m
CONFIG_USB_CHIPIDEA_HOST=y
CONFIG_USB_CHIPIDEA_DEBUG=y
The reason is chipidea host uses symbol from ehci, but ehci
is not compiled. Let the chipidea host depend on
ehci even it is built as module.
