Forced Fast Charge for Samsung Note 3 v1.1 by Yank555.lu

- redone fast charge for new KK kernel sourcedrop

SysFS interface :

 * /sys/kernel/fast_charge/force_fast_charge (rw)
 *
 *   0 - disabled (default)
 *   1 - substitute AC to USB
 *   2 - use custom mA configured through sysfs interface (see below)
 *
 * /sys/kernel/fast_charge/ac_charge_level (rw)
 *
 *   rate at which to charge when on AC (1.0A/h to 2.1A/h)
 *
 * /sys/kernel/fast_charge/usb_charge_level (r/w)
 *
 *   rate at which to charge when on USB (0.460A/h to 1.0A/h)
 *
 * /sys/kernel/fast_charge/failsafe (rw)
 *
 *   0 - disabled - allow anything up to 2.1A/h to be used as AC / USB custom current
 *   1 - enabled  - behaviour as described above (default)
 *
 * /sys/kernel/fast_charge/ac_levels (ro)
 *
 *   display available levels for AC (for failsafe enabled mode)
 *
 * /sys/kernel/fast_charge/usb_levels (ro)
 *
 *   display available levels for USB (for failsafe enabled mode)
 *
 * /sys/kernel/fast_charge/version (ro)
 *
 *   display fast charge version information
 *
 * /sys/kernel/fast_charge/info (ro)
 *
 *   display complete fast charge configuration in human readable format

mdnie: HIJACK MDNIE Profile v1.0a (Yank555.lu)

- added WHATHUB's new control interface keeping the current interface at the same time (stay open)

mdnie lite control: revert back to stocklike disabled by default (Yank555.lu)

mdnie lite control: update single control for black level

- black is applied as a delta to actual black RGB values (-128 to +128)

mdnie lite control: add single control for black level

- slightly adapted to keep copy_mode (Yank555.lu)
- black kept at 0 by default as Natural is kept as base calibration (Yank555.lu)

mdnie lite control: override for all samsung scenarios and profiles (WhatHub)

- slightly adapted to keep copy_mode (Yank555.lu)

mdnie lite control: adjust calibration (WhatHub)

- slightly adapted to keep copy_mode (Yank555.lu)

Simple switchable mdnie lite control interface

- make hijacking STANDARD mode sysfs switchable, disabled by default (Yank555.lu)
- add copy curve information from existing mode
- add copy full mode from existing mode

Sysfs Interface : /sys/class/mdnie/mdnie/...

Simple mdnie lite control interface (WhatHub)

- mdnie lite control: use standard mode instead of movie mode
