Change subject: drivers/generic: Add new driver for power resource pseudo device
......................................................................

Patch Set 7:

I am still looking through the changes. But at minimum, I think we should split this CL into 3-4 separate changes:
1. Refactoring of acpi_device_add_power_res(). Addition of acpi_add_power_states(), acpi_add_scoped_power_res(), acpigen_write_power_states() and update the callers.
2. Change for scan_generic_bus()
3. Addition of new driver for power resource
4. Update current users of acpi_device_add_power_res() to use the new driver.
