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.
