[PATCH 17/18] arm64: versal-net: Look up eMMC device in boot_targets_setup()

[Michal Simek]

The EMMC_MODE case set bootseq from dev_seq(dev) without ever assigning
dev, so it used an uninitialized pointer and produced a bogus device
sequence in boot_targets.

eMMC is wired to the SD1 controller (mmc at f1050000, see
versal-net-mini-emmc.dts). Look that device up like the SD cases do
before using its sequence number.
