Subject: [PATCH] perf: MARVELL_CN10K_TAD_PMU should depend on ARCH_THUNDER

The Marvell CN10K Last-Level cache Tag-and-data Units (LLC-TAD)
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.

Fixes: 036a7584bede317d ("drivers: perf: Add LLC-TAD perf counter support")

Applied to will (for-next/perf), thanks!
