[PATCH v2 0/3] lib: sbi_pmu: SBI v3.0 PMU error code fixes

This series fixes several places where the PMU extension returns
error codes that do not match the SBI v3.0 specification, chapter 11.

Changes in v2:
 - Added patch 3/3: reject reserved flag bits in counter start/stop,
   propagate ALREADY_STARTED/ALREADY_STOPPED, and report firmware
   events as supported in event_get_info.
 - Patches 1/3 and 2/3 are unchanged from their v1 submissions.

This series supersedes the two standalone v1 patches.

David E. Garcia Porras (3):
  lib: sbi_pmu: Return invalid param error for reserved event_idx bits
  lib: sbi_pmu: Match raw event selector only against raw event map
    entries
  lib: sbi_pmu: Fix counter and event info error codes as per SBI v3.0
    spec
