[PATCH] hw/acpi: specify 64-bit acpi table

[Jason A. Donenfeld]

SSDTs cannot address 64-bit physical addresses in 32-bit tables, so we
increment the revision to '2' so that these larger addresses are
addressable. This matters because the DSDT revision represents the
maximum capability of all other SSDTs. This is also what arm does.
