x86/platform/intel-mid: Extend PWRMU to support Penwell
Intel Penwell is one of the first SoCs in Intel MID series. It has slightly older version of PWRMU IP, though it is compatible with one found on Intel Tangier. Since we are not using (yet) any advanced stuff in the driver we may safely re-use what it's done for Intel Tangier for now. Extend PWRMU driver to support Intel Penwell by adding PCI ID and re-using existing ->set_initial_state() function.
