perf: add missing MODULE_DESCRIPTION() macros

With ARCH=x86, make allmodconfig && make W=1 C=1 reports:
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/perf/arm-ccn.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/perf/fsl_imx8_ddr_perf.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/perf/marvell_cn10k_ddr_pmu.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/perf/arm_cspmu/arm_cspmu_module.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/perf/arm_cspmu/nvidia_cspmu.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/perf/arm_cspmu/ampere_cspmu.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/perf/cxl_pmu.o

Add the missing invocation of the MODULE_DESCRIPTION() macro to all
files which have a MODULE_LICENSE().

This includes drivers/perf/hisilicon/hisi_uncore_pmu.c which, although
it did not produce a warning with the x86 allmodconfig configuration,
may cause this warning with arm64 configurations.
