x86: new Intel atom SOC power management controller driver

From: Aubrey Li <[email protected]>

The Power Management Controller (PMC) controls many of the power management features present in the SoC. This driver provides the power off functionality and s0ix residency control, also provides the SOC device state and platform sleep state observation via debugfs.

v3:
- split the driver into tree pieces: the power off functionality, the s0ix residency control, and the debugfs exports.

v2:
- allow pmc_atom and lpc_ich to work at the same time.
