hwrng: cavium - HW_RANDOM_CAVIUM should depend on ARCH_THUNDER
[ Upstream commit ab7d88549e2f7ae116afd303f32e1950cb790a1d ]
The Cavium ThunderX Random Number Generator is only present on Cavium
ThunderX 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 SoC support.
