Add all functions to read each SOM option from the EEPROM
image and detect whether it's the correct product for this
image.

Commit aa7858fe5e2e ("board: phytec: som_detection: move definitions to
source file") moved function definitions from header to source file.
Makefile however was not updated to unconditionally (from
[..]_SOM_DETECTION) build the imx8 and phytec som detection units.
Also remove unused includes that cause build failures on arm 32bit
boards. SoM detection shall support 32bit boards as well, but arch
specific code should not be included in the generic module.

Recent shipped PHYTEC SoMs come with an i2c EEPROM containing
information about the hardware such as board revision and variant.
This can be used for RAM detection and loading device tree overlays
during kernel start.
