platform/x86: drop deprecated asus_acpi driver

asus_acpi only support old models, it has been deprecated since
2009 in favor of asus-laptop, it's not built by any (sane) distro,
so it is time to say good bye.

Thanks to Julien Lerouge and Karol Kozimor for the work they have
done on it, I would never have wrote asus-laptop and other asus
related drivers without asus_acpi.

-	  This driver provides support for extra features of ACPI-compatible
-	  ASUS laptops. As some of Medion laptops are made by ASUS, it may also
-	  support some Medion laptops (such as 9675 for example).  It makes all
-	  the extra buttons generate standard ACPI events that go through
-	  /proc/acpi/events, and (on some models) adds support for changing the
-	  display brightness and output, switching the LCD backlight on and off,
-	  and most importantly, allows you to blink those fancy LEDs intended
-	  for reporting mail and wireless status.
-
-	  Note: display switching code is currently considered EXPERIMENTAL,
-	  toying with these values may even lock your machine.
-
-	  All settings are changed via /proc/acpi/asus directory entries. Owner
-	  and group for these entries can be set with asus_uid and asus_gid
-	  parameters.
-
-	  More information and a userspace daemon for handling the extra buttons
-	  at <http://acpi4asus.sf.net>.
-
-	  If you have an ACPI-compatible ASUS laptop, say Y or M here. This
-	  driver is still under development, so if your laptop is unsupported or
-	  something works not quite as expected, please use the mailing list
-	  available on the above page (acpi4asus-user@lists.sourceforge.net).
-
-	  NOTE: This driver is deprecated and will probably be removed soon,
-	  use asus-laptop instead.
