stdlib: write device tree after setting up bootloader in ARMBoard
The generation of the device tree in an arm system requires knowing
cpu-release-addr property, which is only available after setting up
the bootloader.
cpu-release-addr specifies where the secondary CPUs spin/sleep(?) before
being waken up by the kernel.
The incorrect cpu-release-addr causes booting an arm system using the
standard library with the arm's provided bootloader+linux_kernel to
fail to regconize more than 1 core.
