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.

According to "Designing Cards and Drivers for the Macintosh Family" any attempt
to access an unimplemented address location on Nubus generates a bus error. MacOS
uses a custom bus error handler to detect empty Nubus slots, and with the current
implementation assumes that all slots are occupied as the Nubus transactions
never fail.
Switch nubus_slot_ops and nubus_super_slot_ops over to use {read,write}_with_attrs
and hard-code them to return MEMTX_DECODE_ERROR so that unoccupied Nubus slots
will generate the expected bus error.
