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.
