perf/x86/intel: Setup PEBS data configuration and enable legacy groups
Different with legacy PEBS, arch-PEBS provides per-counter PEBS data
configuration by programing MSR IA32_PMC_GPx/FXx_CFG_C MSRs.
This patch obtains PEBS data configuration from event attribute and then
writes the PEBS data configuration to MSR IA32_PMC_GPx/FXx_CFG_C and
enable corresponding PEBS groups.
Please notice this patch only enables XMM SIMD regs sampling for
arch-PEBS, the other SIMD regs (OPMASK/YMM/ZMM) sampling on arch-PEBS
would be supported after PMI based SIMD regs (OPMASK/YMM/ZMM) sampling
is supported.
