Intel-SIG: dmaengine: idxd: Fix kABI for IDXD perfmon cpu hot plug state.

-------------------------------------------------

In commit ("dmaengine: idxd: Add IDXD performance monitor support"), the
introduction of Intel IDXD performance monitor feature adds new CPU hot
plug state 'CPUHP_AP_PERF_X86_IDXD_ONLINE' in the middle of data
structure 'enum cpuhp_state' that causes kABI breakage.

Fix it by reusing other arch's entry for CPUHP_AP_PERF_X86_IDXD_ONLINE
to avoid kABI breakage.
