Added back 192MHz frequency step
Decreased default max CPU frequency from 1566MHz to 1404MHz
Decreased default min CPU frequency from 384MHz to 192MHz
Decreased WiFi voltage from 2.6v to 2.4v

   Thermald: multiple fixes for greatly increased stability (some fixes are not listed here)

   Thermald: fix issue where thermald would throttle you to 384MHz if it was told that your phone was 275 times hotter than the core of the sun (now if thermald detects a temperature over 1000C then it will poll the temperature sensor until it gets a temp less than 1000C)

   Thermald: in an emergency situation your CPU's max frequency will be reset to 1566MHz

   Thermald: fix rare issue where your CPU's max frequency would be reset to 1944MHz
