arm64: versal2: Fix UFS boot command sequence

Browse Source 
The BOOTENV_DEV_UFS macro is incomplete - it only initializes UFS
and scans SCSI devices but does not actually boot anything. This
causes the boot sequence to stop after scsi scan without loading
a kernel.

Update BOOTENV_DEV_UFS to set the devnum environment variable to
the UFS instance number, initialize the device using $devnum, and
delegate the boot process to the shared scsi_boot script. Remove
the explicit scsi scan, as it is already handled by scsi_boot.

This matches the pattern used by other boot device macros and
ensures that UFS devices can successfully boot using the distro
boot framework.
