The AMD MDB Versal2 PCIe controller is only present on AMD Versal2
ARM64-based SoCs. Hence add a dependency on ARM64, to prevent asking
the user about this driver when configuring a kernel for a different
architecture than ARM64.
Fixes: e229f853f5b277a5 ("PCI: amd-mdb: Add AMD MDB Root Port driver")

To be replaced by ARCH_VERSAL, if/when it ever appears for real.
