Since the QSPI driver is not in the Linux 4.4-rc8 and porting the QSPI
driver from Xilinx kernel did not work straight away.
Currently the system boots from MMC/SD and works. I could potentially
modify the uEnv.txt file to boot a MMC/SD root. or we leave as it is and
it is upto user to set up rootfs overlay on MMC/SD/USB.
