linux-dtb: Add simple DTB symlinks for devicetree
* This is similar to the symlinks provided for the kernel image in the /boot directory of a file system. The goal is to have simply named symlinks in /boot that mirror the device tree name in the kernel sources. This is so that programs like U-Boot can easily find the default device tree binary in the /boot directory and use that when booting the kernel. * Use update-alternatives to handle proper creation and removal of the symlinks.
