Log Message:
Arm: Add support for SMC Calling Convention

Arm DEN0028 defines a calling mechanism used with Secure Monitor Call (SMC)
and Hypervisor Call (HVC) instructions. To discover SMCCC, we must:

 1) Find the PSCI conduit (either via ACPI FADT, or Device Tree)
 2) Use PSCI_VERSION to determine whether PSCI_FEATURES is supported
 3) Call PSCI_FEATURES with SMCCC_VERSION to determine the implementation
    version.
