Subject: [PATCH] hwrng: cn10k - HW_RANDOM_CN10K should depend on ARCH_THUNDER

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.

Fixes: 38e9791a02090414 ("hwrng: cn10k - Add random number generator support")
