x86/platform: New Intel Atom SOC power management controller driver The Power Management Controller (PMC) controls many of the power management features present in the Atom SoC. This driver provides a native power off function via PMC PCI IO port. On some ACPI hardware-reduced platforms(e.g. ASUS-T100), ACPI sleep registers are not valid so that (*pm_power_off)() is not hooked by acpi_power_off(). The power off function in this driver is installed only when pm_power_off is NULL.
