arm64: add smc layer to secmon
In order to process PSCI commands SMC instructions need to be
serviced. Provide a simple way for users of SMC to register their
handlers by function.
The SMC layer hooks into the exception processing, however it only
processes AARCH64 SMC calls. All others are ignored.
BUG=chrome-os-partner:32112
BRANCH=None
TEST=Added nop smc call to depthcharge. SMC handled and continue booting
to kernel.
