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.

Versal2 was using wrong GIC base mappings, causing GICR_TYPER reads to
not match EL1 MPIDR. This led U-Boot to walk beyond the per-CPU GICR
frames, access out-of-range addresses, and hit a synchronous exception
during early gic init percpu while booting up on alternate core
i.e., non cpu0.
Update Versal Gen 2 headers to the correct Versal Gen 2 bases.

By default Versal Gen 2 is using memory map where TF-A is placed to DDR and
there is also some space allocated for OP-TEE that's why move default
variable setting out of this location to avoid using it when distro boot is
used for booting.

Add usb_pgood_delay to ensure proper detection of USB devices.
Increase the USB power good delay for versal2 specific boards,
as certain USB sticks may not be detected without it.

Add support for AMD Versal Gen 2. SoC is based on Cortex-a78ae 4 cluster/2
cpu core each. A lot of IPs are shared with previous families. There are
couple of new IP blocks where the most interesting from user point of view
is UFS.
