[PATCH 1/6] [-mm]: ACPI: add a Kconfig option for ACPI procfs interface

[Zhang Rui <rui.zhang@intel.com>]

From: Zhang Rui <rui.zhang@intel.com>

Add a kconfig option CONFIG_ACPI_PROCFS to make procfs interface a configurable attribute of ACPI.
No procfs interface is actually deprecated, and no sysfs interface is added in this patch.
CONGI_ACPI_PROCFS is used to mark procfs interface as deprecated once the same function is duplicated in sysfs.
