spl:falcon:trats Update Trats default board configuration file to support FALCON MODE

Browse source 
Support for a new command (defined at envs) - spl_export generates
the ATAGS image necessary for fast boot. Afterwards, it is stored
at ext4 partition.

Generated image format:
CRC [4B] SIZE [4B] PAYLOAD(ATAGS/DT) [SIZE]

Remarks:
- CRC is calculated only for PAYLOAD
- SIZE is the size of PAYLOAD

It is important to adjust ${splsize} when large image is generated.
It is defined as hex, since ext4 related commands expect it.

The ${spladdr} environment variable corresponds to
CONFIG_SYS_SPL_ARGS_ADDR

Additionally definitions for DFU have been refactored and support for
EFI has been added as well.
