[PATCH v1] tpm2: add longer timeout for verify signature command

[amirmizi6]

From: Amir Mizinski <amirmizi6@xxxxxxxxx>

TPM2_CC_VERIFY_SIGNATURE(0x177) Current timeout does not apply to usage with
RSA 3070-bit keys.
Additional time may be required for usage with RSA 3070-bit keys. Therefore, the
timeout of TPM2_CC_VERIFY_SIGNATURE is set to 3 minutes (TPM_LONG_LONG).
