board: tqma6: add kernel device tree handling for environment
Set the environment variable 'fdtfile' depending on ENET workaround
detection.
The function tqma6_get_fdt_configuration is implemented to be reusable
for configuration detection in multi-DTB FIT image and therefore returns
the devicetree name without the '.dtb' ending.
Set fdtfile only if CONFIG_ENV_VARS_UBOOT_RUNTIME_CONFIG is enabled and it
is currently unset.
The model string is loaded from the device tree variant. Therefore, the
overriding of the model string is being removed.
