Pranav Tilak af5c2b759e arm64: versal2: Fix emmc boot mode boot_target issue
The eMMC boot device controller on Versal2 requires device pointer
initialization before accessing its sequence number. The EMMC_MODE case
was using dev_seq(dev) on an uninitialized pointer, causing corrupted
boot_targets entries (mmc7f7fbfbf instead of mmc0/mmc1).

Add uclass_get_device_by_name() call to properly initialize the device
pointer before reading the sequence number. The dev sequence number is
determined at runtime based on DT aliases.

Fix boot_targets corruption in eMMC boot mode, allowing proper boot
device selection instead of falling back to JTAG mode.
