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+	  they have been replaced by functions in /sys.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/fadt (/sys/firmware/acpi/tables/FACP)
+	  /proc/acpi/debug_layer (/sys/module/acpi/parameters/debug_layer)
+	  /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/
