v1:
	* https://lore.kernel.org/all/20241024233035.7979-1-ilkka@os.amperecomputing.com/

v2:
	* Doesn't use read_cpuid_implementor() anymore as that was broken and
	  unnecessary.
	* Convert AmpereOne source field to matching common source fields to
	  avoid duplicating the code.
	* Rebased on top of perf-tools-next/perf-tools-next (ba993e5ada1d)
	* https://lore.kernel.org/all/20241031213533.11148-1-ilkka@os.amperecomputing.com/

v3:
	* Changed source mapping to simple switch statement
	* Dropped is_xyz() stuff
	* Added table to map midr to data source decoding function
	* https://lore.kernel.org/all/20241106193740.6159-1-ilkka@os.amperecomputing.com/

v4:
	* Split midr/decoding function table
	* Made AmpereOne DS decoding function to ignore unknown sources
