Add DSDT node for AppleSMC
AppleSMC (-device isa-applesmc) is required to boot OS X guests.
OS X expects a SMC node to be present in the ACPI DSDT. This patch
adds a SMC node to the DSDT, and dynamically patches the return value
of SMC._STA to either 0x0B if the chip is present, or otherwise to 0x00,
before booting the guest.
