arm64: versal: Fix emmc boot mode boot_target issue

Emmc boot devcie is mounted to sdhci@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@f1050000 controller.
Dev seq number is setup based on DT aliases that's why needs to be setup at
run time.
