Bug description:
[SRU Justification]
[Impact]
Missing support for of AMD Secure Processor device for PCI ID 0x14CA.
[Fix]
A patch is being proposed in upstream and CC-ed stable.
[Test Case]
Without a proper fix, following error appears in dmesg:
ccp 0000:02:00.5: tee: missing driver data

[Where problems could occur]
This adds a new driver data entry to support ccp device that provides
both sev and tee feature at the same time.

nominated for fix.
