ACPICA: Support for custom ACPICA build for ACPI 5 reduced hardware
Add ACPI_REDUCED_HARDWARE flag that removes all hardware-related code (about 10% code, 5% static data). Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
