This patch adds smc and hvc commands, that allow issuing Secure Monitor
Calls and Hypervisor Calls conforming to the ARM SMC Calling Convention.
Add Kconfig items to allow each command can be individually enabled.

Sorry for not catching this before, in both cases we should depend on
ARM_SMCC as that's what provides the underlying functions and is
available on both ARMv7 and ARMv8.
Ah, you're right, I should had spotted that too. Will replace the ARM64
dependendy with ARM_SMCCC and issue another patch.
Thanks
