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,
