Input: wacom - add Intuos4 LED and OLED control
This commit enables control of the LEDs and OLED displays found on the Wacom Intuos4 M, L, and XL. For this purpose, a new "wacom_led" attribute group is added to the sysfs entry of the USB device. This "wacom_led" group only shows up when the correct device (M, L, or XL) is detected. The attributes are described in Documentation/ABI/testing/sysfs-wacom Signed-off-by: Eduard Hasenleithner <eduard@hasenleithner.at> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

+ this file returns 1 if tablet reports in high speed mode
+ or 0 otherwise. Writing to this file one of these values

+Description:
+ Attribute group for control of the status LEDs and the OLED
+ displays found on the Wacom Intuos 4 M, L, and XL tablets. This
+ attribute group is not available for other Wacom tablets.
+ Therefore its presence implicitly signifies the presence of
+ said LEDs and OLED displays on the tablet device.

+Description:
+ When writing a 1024 byte raw image in Wacom Intuos 4
+ interleaving format to the file, the image shows up on Button N
+ of the device. The image is a 64x32 pixel 4-bit gray image. The
+ 1024 byte binary is split up into 16x 64 byte chunks. Each 64
+ byte chunk encodes the image data for two consecutive lines on
+ the display. The low nibble of each byte contains the first
+ line, and the high nibble contains the second line.
