Add some pre-computed binary MRC data so that memory init does not take nearly 30 seconds to run on the first boot.
At present every time U-Boot is flashed, coral takes nearly 30 seconds to boot the first time. Add an initial MRC cache to speed this up. This is somewhat dangerous since the data is taken from just one board, so your mileage may vary. This patch should not be applied.
