A warning as below may be occasionally triggered in an ADL machine when
these conditions occur:

 - Two perf record commands run one by one. Both record a PEBS event.
 - Both runs on small cores.
 - They have different adaptive PEBS configuration (PEBS_DATA_CFG).

  [ ] WARNING: CPU: 4 PID: 9874 at arch/x86/events/intel/ds.c:1743 setup_pebs_adaptive_sample_data+0x55e/0x5b0
  [ ] RIP: 0010:setup_pebs_adaptive_sample_data+0x55e/0x5b0
  [ ] Call Trace:
  [ ]  <NMI>
  [ ]  intel_pmu_drain_pebs_icl+0x48b/0x810
  [ ]  perf_event_nmi_handler+0x41/0x80
  [ ]  </NMI>
  [ ]  __perf_event_task_sched_in+0x2c2/0x3a0

Different from the big core, the small core requires the ACK right
before re-enabling counters in the NMI handler, otherwise a stale PEBS
record may be dumped into the later NMI handler, which trigger the
warning.

Add a new mid_ack flag to track the case. Add all PMI handler bits in
the struct x86_hybrid_pmu to track the bits for different types of
PMUs.  Apply mid ACK for the small cores on an Alder Lake machine.

The existing hybrid() macro has a compile error when taking address of
a bit-field variable. Add a new macro hybrid_bit() to get the
bit-field value of a given PMU.
