[Scott Garman]

From: Zhenhua Luo <b19537 at freescale.com>

    including following enhancement:
    * support multi-dtb build
    * skip dtb build and install when KERNEL_DEVICETREE is empty
    * print a warning message when specified dts file is not available

(From OE-Core rev: 66f7921f34dfa8b3c7f8f7184715214164f3f8b0)
