When a system contains multiple USB controllers, the global ci_role_switch
variable may be overwritten by subsequent driver initialization code.
This can cause issues in the following cases:
- The 2nd ci_hdrc_probe() sees ci_role_switch.fwnode as non-NULL even
though the "usb-role-switch" property is not present for the controller.
- When the ci_hdrc device is unbound and bound again, ci_role_switch
fwnode will not be reassigned, and the old value will be used instead.
Convert ci_role_switch to a local variable to fix these issues.
