Add support for keyboard backlight found in Asus U50VG.
The SMC driver for the Apples does it via LED. To be
consistent with that we create /sys/class/leds/asus::kbd_backlight/
to control the keyboard backlight.
SLKB and GLKB are used to get/set the backlight. On
the U50VG is supports 4 brightness level, but this may
change with other models.
SLKB take a 8 bit integer where the higher bit is used
to toggle the backlight, and the over 7 bits control the
brightness level.

to support keyboard backlight/led.

Makes asus-laptop platform device the parent device of

This patch adds a .notify() method. The presence of .notify() causes
Linux/ACPI to manage event handlers and notify handlers on our behalf,
so we don't have to install and remove them ourselves.
This driver apparently relies on seeing ALL notify events, not just
device-specific ones (because it used ACPI_ALL_NOTIFY). We use the
ACPI_DRIVER_ALL_NOTIFY_EVENTS driver flag to request all events.

KEY_STOP is now KEY_STOPCD
It's the correct key to stop a media
BTN_EXTRA is now KEY_SCREENLOCK:
The laptop manual tells us that this key is for screenlock
KEY_TV is now KEY_PROG1
So it can be reported to X server

Move x86 platform specific drivers from drivers/misc/
to a new home under drivers/platform/x86/.
The community has been maintaining x86 vendor-specific
platform specific drivers under /drivers/misc/ for a few years.
The oldest ones started life under drivers/acpi.
They moved out of drivers/acpi/ because they don't actually
implement the ACPI specification, but either simply
use ACPI, or implement vendor-specific ACPI extensions.
In the future we anticipate...
drivers/misc/ will go away.
other architectures will create drivers/platform/<arch>
