perf tools: Add a place to put kernel config fragments for test runs
Defconfig doesn't give full coverage for a perf test run, so these can be merged with defconfig to do so. It's not complete yet, but is a starting point as a place to add to when a specific test needs something extra to run.

+This folder is for kernel config fragments that can be merged with
+defconfig to give full test coverage of a perf test run. This is only
+an optimistic set as some features require hardware support in order to
+pass and not skip.
+
+'config' is shared across all platforms, and for arch specific files,
+the file name should match that used in the ARCH=... make option.
