[U-Boot] [PATCH 5/5] mx6cuboxi: Load the correct 'fdt_file' variable

[Fabio Estevam <festevam@gmail.com>]

From: Fabio Estevam <fabio.estevam@freescale.com>

Instead of hardcoding the 'fdt_file' variable, let's introduce a new
function - build_dts_name(), that can build the dtb filename on the fly.
