The Marvell CN10K True Random Number generator is only present on
Marvell CN10K SoCs, and not available as an independent PCIe endpoint.
Hence add a dependency on ARCH_THUNDER, to prevent asking the user about
this driver when configuring a kernel without Cavium Thunder (incl.
Marvell CN10K) SoC support.
