Add support for different RAM sizes and speed grades on the
phyCORE-i.MX8MP.
Add support for 1GB 1.5GHz, 1GB 2GHz, 4GB 1.5GHz,
4GB 2GHz and 8GB 2GHz RAM.
The RAM size and speed grade is detected by the information
stored in the EEPROM on the SoM.

Due to PCB layout constraints in PCB revisions until including 1549.2,
a RAM frequency of 2 GHz can cause rare instabilities. Set the RAM
frequency to 1.5 GHz to achieve a stable system under all conditions.
