After commit b09b5224 ("usb: chipidea: implement platform shutdown callback") and commit 43a40457 ("usb: chipidea: host: set host to be null after hcd is freed") a NULL pointer dereference is caused on i.MX23 during shutdown. So ensure that role is set to CI_ROLE_END and we finish interrupt handling before the hcd is deallocated. This avoids the NULL pointer dereference.
