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

cpufreq: mcm8974: raise all voltages by 25mV (back to JB kernel levels)
cpufreq: OC up to 2.5GHz (Yank555.lu)

- added 2.34GHz, 2.42 GHz and 2.50GHz step
- max. voltage increased from 1100000 to 1200000 microVolt
