From: Hao Zhang <[email protected]>

Build recovery kernel image and k2hk-evm dtb image for Keystone II
devices.

Normally when kernel is booted by u-boot,  u-boot takes care to reserve
free memory space in the DTB, which is required for kernel. For recovery
image, user has to add the free space manually using dtc compiler.
