ENGR00112918-1: Add support for SW controlled frequency scaling.
Add 3 working points for AHB frequencies: 24Mhz, 83.3MHz and 133MHz.
The switching between these modes is done dynamically based on what modules
are active.
Also changed NAND to work in asymmetric mode since in symmetric mode, NFC does
not work correctly when its clocks are changed dynamically.
