--------------------------------

commit 6fb9e1d9 upstream.

System like Android allow user control power role from UI, it is possible
to implement application base on typec uevent to refresh UI, but found
there is chance that UI show different state from typec attribute file.

In typec_set_pwr_opmode(), when partner support PD, there is no uevent
send to user space which cause the problem.

Fix it by sending uevent notification when change power mode to PD.
