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.
