soma5d36/36mp uboot and bootstrap sync'd with upstream
This merge is to update the bootstrap and uboot for the a5d36, and to update the bootstrap for the soma536mp, uboot is being held back at this time for the a536mp for the time being due to the ethernet mac on cadence gem failing to connect at mii phy modes
