Firmware Framework for Arm A-profile (FF-A) is a messaging framework
for Arm-based systems, and in the context of the TPM CRB driver is used
to signal 'start' to a CRB-based TPM service which is hosted in an
FF-A secure partition running in TrustZone.
These patches add support for the CRB FF-A sta
Refactor TPM idle check to tpm_crb_has_idle(), and reduce paraentheses
usage in start method checks
