[U-Boot] [patch v2 1/2] pxe: Fix pxe boot with FIT image
From: York Sun york.sun@nxp.com
When FIT image is used, a single image provides kernel, device tree and optionally ramdisk. Argc and argv need to be adjusted to support this.
Test cases: 1. Booting with legacy images 2. Booting with legacy images without initrd 3. Booting with FIT image Test commands: 1. pxe get && pxe boot 2. sysboot

Use environment variable "kernel_addr_r" to indicate the location in RAM where FIT image will be stored. Use label command "kernel" to indicate which <path> the FIT image at.
