Adding the unit address to the memory node was causing the below error:

(8 bytes) (#address-cells == 2, #size-cells == 2)

Further debugging showed that this was due to the memory node added by
default to skeleton.dtsi which was being included in keystone-k2g.dtsi.
Adding a missing node was all that was needed to remove this deprecated
dtsi file from the SoC dtsi. With skeleton.dtsi removed the dtc compiler

Now with support for U-boot runtime dtb selection each board needs to

For K2G, runtime DTB selection utilizes the embedded_dtb_select function.
Therefore, define the function which will perform a EEPROM read and then
retries selecting the correct dtb now that it can detect which board its
on. For other Keystone devices use an empty function since they will still
use the embedded FIT functionality but their FIT will only contain a single
dtb.

Most production K2G boards do not have their EEPROM programmed. Therefore,
perform a test to verify a K2G GP is currently being used and if it is then
set the values normally set by a EEPROM read.
