From: Fabio Estevam <fabio.este...@freescale.com>
Since kernel 3.15 there are two dtb's for the imx53-qsb board:
imx53-qsb.dtb - For the boards with DA9053 PMIC
imx53-qsrb.dtb - For the boards with MC34708 PMIC
Change the 'fdt_file' dynamically, so that the correct dtb can be used depending
on the board variant.
