ACPI: Kconfig: CONFIG_ACPI_PROCFS now defaults to N

delete "default y" from CONFIG_ACPI_PROCFS
(effectively making the default 'N')

List exactly what /proc files this option controls,
and clarify that it doesn't change non-deprecated files.

-         The Procfs interface for ACPI is made optional for backward compatibility.
-         As the same functions are duplicated in the sysfs interface
-         and this proc interface will be removed some time later,
-         it's marked as deprecated.
-         ( /proc/acpi/debug_layer && debug_level are deprecated by
-           /sys/module/acpi/parameters/debug_layer && debug_level.
-           /proc/acpi/info is deprecated by
-           /sys/module/acpi/parameters/acpica_version )
+         For backwards compatibility, this option allows
+         depricated /proc/acpi/ files to exist, even when
+         they have been replaced by functions in /sys.
+         The deprecated files (and their replacements) include:
+
+         /proc/acpi/info (/sys/modules/acpi/parameters/acpica_version)
+         /proc/acpi/dsdt (/sys/firmware/acpi/tables/DSDT)

+         /proc/acpi/debug_level (/sys/module/acpi/parameters/debug_level)
+
+         This option has no effect on /proc/acpi/ files
+         and functions which do not yet exist in /sys.
+
+         Say N to delete /proc/acpi/ files that have moved to /sys/
