acpi: avoid potential uninitialized access to cpu_hp_io_base
When building QEMU with Mingw64 toolchain I see a warning
CC x86_64-softmmu/hw/i386/acpi-build.o
hw/i386/acpi-build.c: In function 'acpi_build':
hw/i386/acpi-build.c:1138:9: warning: 'pm.cpu_hp_io_base' may be used uninitialized in this function [-Wmaybe-uninitialized]
aml_append(crs,
^
hw/i386/acpi-build.c:1666:16: note: 'pm.cpu_hp_io_base' was declared here
AcpiPmInfo pm;
^
In acpi_get_pm_info() some of the fields are pre-initialized
to 0, but this one was missed.
