[OE-core] [PATCH 1/2] 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.

* Updated in version 2
* Changed the variable names to use variables that match the
do_install and do_deploy more closely for consistency. i.e.
using DTB_SYMLINK_NAME instead of DTB_NAME.
* The above changes were based on input from:
* Darren Hart <dvhart at linux.intel.com>
* Bruce Ashfield <bruce.ashfield at windriver.com>
