CCGx controller used on NVIDIA GPU card has two separate display

prohibits using separate display altmode.
Current UCSI Type-C framework expects only one display altmode for

Hi Johan,
Sorry for the slow reply. Thanks for the feedback.
I've amended the patch and is below. I think I've done all of your
suggestions and looks more Linux Kernelish style.

Whenever we have a request in flight, we can move it to the cancelled

find.

This reverts commit 25ad17d692ad54c3c33b2a31e5ce2a82e38de14e,
as we will be cherry-picking a number of changes from upstream
that allows us to later cherry-pick the same fix from upstream
rather than using this modified backported version.
