mdnie lite control: initial control interface (version 1.3)

Version 1.3: updated sysfs interface
Version 1.2: fixed compatibility with samsung NA6 (kitkat) source.

sysfs controls for RGBCMYWK channel and "sharpen" effect:
[/sys/class/mdnie/mdnie/*]
(* = red, green, blue, cyan, magenta, yellow, white, black, sharpen)

override for all samsung modes and profiles:
[echo 1 > /sys/class/mdnie/mdnie/override]

[echo 255 150 75 > /sys/class/mdnie/mdnie/red]
(255 = red; 150 = green; 75 = blue)

Copy color profile from existing mdnie profile:
(echo x > /sys/class/mdnie/mdnie/copy_mode)

where X equals :
- 0 = Standard
- 1 = Natural
- 2 = Movie

copy gamma curve from existing mdnie profile:
[echo x > /sys/class/mdnie/mdnie/gamma_curve]

where X equals :
- 0 = Movie
- 1 = Dynamic

Idea based on (mDNIe colour and brightness control) by AndreiLux.
Thanks to Yank555.lu for his hijack and mode copy implementation.
LED eXtended ConTRoLs v1.1 (Yank555.lu)

 - Allow for customized brightness and delayon / delayoff control by user

 * SysFs interface :
 * -----------------
 *
 * /sys/class/sec/led/led_intensity : 0 - 255 (100 = stock)
 *
 *     Set the relative intensity of the LED respecting the userspace's request
 *
 * /sys/class/sec/led/led_speed_on  : 1 - 5 (1 = stock)
 *
 *     Devider for delayon  (1 - 5 times shorter than requested by userspace)
 *
 * /sys/class/sec/led/led_speed_off  : 1 - 5 (1 = stock)
 *
 *     Devider for delayoff (1 - 5 times shorter than requested by userspace)
 *
 * /sys/class/sec/led/led_xctrl_version :
 *
 *     Display the current version of the eXtended ConTRoLs
 *
 * /sys/class/sec/led/led_xctrl_info :
 *
 *     Display the current settings in human readable format
hlte: power enhancement for wacom hardware.

* always disable digitizer when the pen is inserted
