x86: Fix TPM driver to work with multiple vendor TPMs
- Fix bug in traversal of vendor name list.
- Sending "command ready" needs additional logic to handle
TPMs that need that bit set twice: once to empty the read
FIFOs and once to actualy set command ready.
- Certain TPMs need a small delay between requesting locality
and attempting to set command ready or they will hang the bus.
BUG=chrome-os-partner:8558
TEST=manual
Successful boot and suspend/resume with all TPMs listed
in the driver vendor/device list.
