arm64: zynqmp: Fix emmc boot mode boot_target sequence
Emmc boot devcie is mounted to mmc@ff160000 controller on zynqmp.
Detect mmc alias at run time for setting up proper boot_targets
sequence instead of setting boot_targets manually.
Removed setting "modeboot" variable as it not longer need as we
switched to distro boot.
