Xilinx: ARM: Updated boot command to use QSPI

U-boot has to be built differently when it is to be written to
QSPI vs NOR flash. Since both use execute in place mode, the header
in u-boot has to have the address to jump to in flash for the boot
rom to use.

The boot command copies the kernel and root file system from flash
to ram and it has to know which addresses for flash (QSPI or NOR).
