Bryan O'Donoghue 3e63cff384 usb: roles: Switch on role-switch uevent reporting ...

Right now we don't report to user-space a role switch when doing a
usb_role_switch_set_role() despite having registered the uevent callbacks.

This patch switches on the notifications allowing user-space to see
role-switch change notifications and subsequently determine the current
controller data-role.

example:
PFX=/devices/platform/soc/78d9000.usb/ci_hdrc.0

root@somebox# udevadm monitor -p

KERNEL[49.894994] change $PFX/usb_role/ci_hdrc.0-role-switch (usb_role)
ACTION=change
DEVPATH=$PFX/usb_role/ci_hdrc.0-role-switch
SUBSYSTEM=usb_role
DEVTYPE=usb_role_switch
USB_ROLE_SWITCH=ci_hdrc.0-role-switch
SEQNUM=2432
