hw/i386/acpi: Declare pc_madt_cpu_entry() in 'acpi-common.h'

Since pc_madt_cpu_entry() is only used by:
 - hw/i386/acpi-build.c   // single call
 - hw/i386/acpi-common.c  // definition
there is no need to expose it outside of hw/i386/.
Declare it in "acpi-common.h".
acpi-build.c doesn't need "hw/i386/pc.h" anymore.
