acpi: fix buffer overrun on migration
ich calls acpi_gpe_init with length ICH9_PMIO_GPE0_LEN so
ICH9_PMIO_GPE0_LEN/2 bytes are allocated, but then the full
ICH9_PMIO_GPE0_LEN bytes are migrated.
As a quick work-around, allocate twice the memory.
We'll probably want to tweak code to avoid
migrating the extra ICH9_PMIO_GPE0_LEN/2 bytes,
but that is a bit trickier to do without breaking
migration compatibility.
