This series add,
1. support for ACPI RASF(RAS feature table) PCC interfaces
to communicate with the HW patrol scrubber in the platform,
as per ACPI 5.1 & upwards revision. Section 5.2.20.

2. support for ACPI RAS2(RAS2 feature table), as per
ACPI 6.5 & upwards revision. Section 5.2.21.

3. scrub driver supports configuring parameters of the memory
scrubbers in the system. This driver has been implemented
based on the hwmon subsystem.

The features have tested with RASF and RAS2 emulation in the QEMU.
