Subject: [PATCH] Revert "usb: cdns3: core: quit if it uses role switch class"

This reverts commit 50642709f6590fe40afa6d22c32f23f5b842aed5.

This commit breaks hardware based role switching on TI platforms.
cdns->role_sw is always going to be non-zero as it is a pointer
to the usb_role_switch instance. Some other means needs to be used
if hardware based role switching is not required by the platform.
