Currently, phytec_get_product_name() function only takes care of PCM
SoM type, however in case of PCL, KSM or KSP SoM type it will return
error:

Add support for other SoM types as defined in phytec_som_type_str enum

While at it, also simplify switch case statements by grouping them

This patch set adds the phyCORE AM62Ax board support and documenation to

The phyCORE-AM62Ax is a SoM (System on Module) featuring TI's AM62Ax SoC. It can
be used in combination with different carrier boards. This module can come

A development Kit, called phyBOARD-Lyra is used as a carrier board reference
