usb: typec: add missing uevent when partner support PD
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.
