tpm: Provide a generic means to override the chip returned timeouts
commit 8e54caf407b98efa05409e1fee0e5381abd2b088 upstream.
Some Atmel TPMs provide completely wrong timeouts from their
TPM_CAP_PROP_TIS_TIMEOUT query. This patch detects that and returns
new correct values via a DID/VID table in the TIS driver.
Tested on ARM using an AT97SC3204T FW version 37.16
[PHuewe: without this fix these 'broken' Atmel TPMs won't function on
older kernels]
