platform/x86/amd/pmf: Prevent TEE errors after hibernate

Browse source 
[ Upstream commit 48d229c704 ]

After resuming from hibernate, TEE commands can time out and cause PSP
disables. Fix this by reinitializing the Trusted Application (TA) and
cancelling the pb workqueue in the hibernate callbacks to avoid these
errors.
