From: Fabio Estevam <fabio.este...@freescale.com>
Instead of hardcoding the 'fdt_file' variable, let's detect the SoC and
board variant on the fly and change the dtb name.
Based on a patch from Rabeeh Khoury.

Changes since v2:
- Add Rabeeh's Signed-off-by
Changes since v1:
- Attribute the credit to Rabeeh
- Create a U-boot command for checking if the board is hummingboard
