Revert "ucsi: ucsi_glink: notify partner information"

Browse Source 
This reverts commit 3c3f7244f40d7cf47a350ff23761fa0d4d9cd80f.

UCSI partner alternate_mode and usb type information is not needed anymore
for clients like USB redriver as it will be controlled by role switch in
ucsi framework, hence removing it.
