acpi: pnp: add ACPI_RESOURCE_TYPE_SERIAL_BUS as a valid type

From: Harb Abdulhamid <[email protected]>

An error message is printed for resources of type 19, which is a valid supported resource type. The Firmware Test Suite tool (fwts) reports this as a test failure. This change fixes the false test failures for ASL that use type 19 (ACPI_RESOURCE_TYPE_SERIAL_BUS) resources.
