Xilinx: ARM: update upper memory limit for dt and ramdisk

By default u-boot will try to load the device tree and
the ramdisk into high memory. This sets up the limits
to reserve some high memory (above 512MB) so that the
items are not loaded higher than that.

The Xilinx TRD uses video memory up high for one example
and if these items are loaded up high the Linux kernel
would not be able to access it.
