Read device unique ID and set environment variable "serial#".
Value would then be passed to kernel through DTB.
To read ID from DTB, kernel is required to have commit:

On STM32F429 gpio PC6/PC7 can be allocated for USART6, as
reported in the comment.
But current code in
drivers/serial/serial_stm32.c
uses a different gpio mapping (PG14/PG9) for USART6.
Fix the comment to match current code in the driver.

This sets the default commands Kconfig to match
include/config_cmd_default.h commands in the common/Kconfig and removes
them from include/configs.
