imx: kontron: Add common function to get HW UIDs from OTPs

The factory provides a CPU UID in the OTPs and the SoM module
and the carrier board might provide additional UIDs in the GP
registers of the OTPs.

Provide a common function to load UIDs from arbitrary OTP
registers and generate a serial number string that is saved
in the "serial#" env variable.
