Subject: [PATCH] perf: MARVELL_CN10K_DDR_PMU should depend on ARCH_THUNDER

The Marvell CN10K DRAM Subsystem (DSS) performance monitor is only
present on Marvell CN10K SoCs. 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,

Applied to arm64 (for-next/fixes), thanks!
