board: dhelectronics: Sync env variable dh_som_serial_number with SN
The env variable "SN" is used to store the serial number on DH electronics
SoMs. New SoMs will use the variable "dh_som_serial_number". To ensure
compatibility, these env variables are synchronized. This is achieved
using callback functions.
