ENGR00162319: MX6 - Add support for updated VDDARM voltages
Set the ARM LDO voltage to 1.225V to run the part at 1GHz.
Also updated the rest of the voltages based on the latest
available working points.
The boards will need to be modified for this change to work
correctly. Please ensure that the VDDARM_IN is set to 1.38V
(using the potentiometer on the ARM2 board or choosing the correct
resistors on the sabrelite boards).
Also added command line option (arm_freq=800) to set the max ARM freq.
Add:
arm_freq=1000 -> to set the max ARM freq to 1GHz
arm_freq=800 -> to set the max ARM freq to 800MHz.
Default max ARM freq is 1GHz. No other values are currently
supported. If your board is not modified, please add the command
line "arm_freq=800' to avoid failures.
