armv8/fsl_lsch2: Add chip power supply voltage setup
Set up chip power supply voltage according to voltage ID.
The fuse status register provides the values from on-chip
voltage ID fuses programmed at the factory. These values
define the voltage requirements for the chip.
Main operations:
1. Set up the core voltage
2. Set up the SERDES voltage and reset SERDES lanes
3. Enable/disable DDR controller support 0.9V if needed
