power: reset: reboot-mode: support multi-word magic
The upstream binding and driver implementation only supports
reboot modes of 32-bit length. This is insufficient for cases where
multiple registers need to be written for the reboot mode to become
active. The i.MX6 is an example for this, the BootROM expects a second
32-bit register to indicate whether the reboot mode in the first is
valid. In preparation for adding support for this to the
syscon-reboot-mode driver. Migrate the reboot-mode core to support this.
