cxl: remove CONFIG_CXL_PMU entry in drivers/cxl/Kconfig
Commit 5d7107c72796 ("perf: CXL Performance Monitoring Unit driver") added the config entries for CXL_PMU in drivers/cxl/Kconfig and drivers/perf/Kconfig, so it can be toggled from multiple locations: [1] Device Drivers -> PCI support -> CXL (Compute Expres Link) Devices -> CXL Performance Monitoring Unit [2] Device Drivers -> Performance monitor support -> CXL Performance Monitoring Unit This complicates things, and nobody else does this. I kept the one in drivers/perf/Kconfig because CONFIG_CXL_PMU controls the compilation of drivers/perf/cxl_pmu.c.
