[PATCH] arm64: versal: Fix emmc boot mode boot_target issue

[Michal Simek]

From: T Karthik Reddy <t.karthik.reddy at xilinx.com>

Emmc boot devcie is mounted to sdhci at f1050000 controller on versal, while
in emmc boot mode, boot tragets are set to mmc0. So removed mmc0 and using
the dev seq number from the sdhci at f1050000 controller.
Dev seq number is setup based on DT aliases that's why needs to be setup at
run time.
