The GIC redistributor base address depends on the part: the 2VM3654
device has 4 APU cores and 3 GIC ITS blocks, which shifts the
redistributor region up compared to the base 8 core / single ITS part.
A single U-Boot binary must therefore pick the right base at runtime
instead of relying on the compile-time GICR_BASE used by the generic
lowlevel_init().
Add a SoC specific lowlevel_init() that reads the PMC TAP IDCODE and
selects GICR_BASE_2VM3654 for the 2VM3654 device, otherwise keeps the
default GICR_BASE. CONFIG_ARMV8_MULTIENTRY is not supported on Versal
Gen 2 so the generic slave handling is intentionally dropped.
