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

ccp 0000:c4:00.2: tee: command 0x5 timed out, disabling PSP
