perf/x86/intel: Mark expected switch fall-throughs
In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. This patch fixes the following warnings: arch/x86/events/intel/core.c: In function ‘intel_pmu_init’: arch/x86/events/intel/core.c:4959:8: warning: this statement may fall through [-Wimplicit-fallthrough=] pmem = true; ~~~~~^~~~~~ arch/x86/events/intel/core.c:4960:2: note: here case INTEL_FAM6_SKYLAKE_MOBILE: ^~~~ arch/x86/events/intel/core.c:5008:8: warning: this statement may fall through [-Wimplicit-fallthrough=] pmem = true; ~~~~~^~~~~~ arch/x86/events/intel/core.c:5009:2: note: here case INTEL_FAM6_ICELAKE_MOBILE: ^~~~ Warning level 3 was used: -Wimplicit-fallthrough=3 This patch is part of the ongoing efforts to enable -Wimplicit-fallthrough.
