Myrrh Periwinkle 3907130abb usb: typec: ucsi: Check if power role change actually happened before handling 
[ Upstream commit b80e7d34c7 ]

The CrOS EC may send a connector status change event with the power
direction changed flag set even if the power direction hasn't actually
changed after initiating a SET_PDR command internally [1]. In practice
this happens on every system suspend due to other changes performed by
the EC [2][3][4], causing suspend to fail.

Fix this by checking if the power role change actually happened before
handling it.
