The series moves the existing access functions to the AM62 Device
Identification fields and adds function for the not yet accessible
fields to be available to all.

This is then used in the Verdin AM62 board code to set the CPU core
voltage according to speed grade to gain more than 100mW power
consumption reduction for the slower speed graded SKUs.
