tpm2: add longer timeouts for creation commands.

Browse source

TPM2_CC_Create(0x153) and TPM2_CC_CreatePrimary (0x131) involve generation
of crypto keys which can be a computationally intensive task. The timeout
is set to 3min. Rather than increasing default timeout a new constant is
added, to not stall for too long on regular commands failures.
