tegra124: Add a stub implementation of the tegra124 SOC. Most things still needs to be filled in, but this will allow us to build boards which use this SOC.

coreboot: introduce boot_device The boot_device is a region_device that represents the device from which coreboot retrieves and boots its stages. The existing cbfs implementations use the boot_device as the intermediary for accessing the CBFS region. Also, there's currently only support for a read-only view of the boot_device. i.e. one cannot write to the boot_device using this view. However, a writable boot_device could be added in the future.
