Revert "cmd: pxe_utils: Check fdtcontroladdr in label_boot"

With the change here, all extlinux.conf files with only "KERNEL
/fitImage" don't work anymore. One common example of this would be those
files generated by thee Poky/OE WIC bootimg-partition bootloader
partition generator.

This reverts commit d5ba6188dfbf6bb68354bec86e483623f1f6dae2.
