This adds reboot-mode support for the AM625 and AM62L SoCs.
We only add usbdfu, emmc and nand for now. Most other boot modes require
additional board specific configuration in bit[9-7], so these have to be
added in a board specific dts. Also we only touch the primary boot mode
and leave the secondary boot mode untouched.
