Subject: [PATCH] converter/ibm_5291 * Restore code from #4483 to working
 order. * #13471 changed MATRIX_ROW_PINS to avoid warnings, rather than
 realizing that it didn't mean the same thing. * #13658 then removed it
 because it wouldn't compile after that. * So, instead rename the PIN macros
 to not conflict with regular matrix scanning.
