Alexander Graf 01e75d8783 allwinner-h3: Switch to SMC as PSCI conduit 
The Allwinner H3 SoC uses Cortex-A7 cores which support virtualization.
However, today we are configuring QEMU to use HVC as PSCI conduit.

That means HVC calls get trapped into QEMU instead of the guest's own
emulated CPU and thus break the guest's ability to execute virtualization.

Fix this by moving to SMC as conduit, freeing up HYP completely to the VM.
