[PATCH 3/3] libata-acpi: update Makefile & Kconfig

[PATCH 3/3] libata-acpi: update Makefile & Kconfig

[Randy Dunlap]

From: Randy Dunlap <randy_d_dunlap@linux.intel.com>

Simplify Makefile.
Add Kconfig help.

Changelog addition:

This option adds support for SATA-related ACPI objects.
These ACPI objects add the ability to retrieve taskfiles
from the ACPI BIOS and write them to the disk controller.
These objects may be related to performance, security,
power management, or other areas.
You can disable this at kernel boot time by using the
option 'libata.noacpi'.
