Port DIRECT_PINS from split_common/matrix.c to matrix.c (#5091)
* Port DIRECT_PINS from split_common/matrix.c to matrix.c * Reorder matrix.c to remove foward declaration and match split_common/matrix.c * Refactor nano to use DIRECT_PINS * Reorder matrix.c to remove foward declaration and match split_common/matrix.c * Add DIRECT_PINS documentation * Reorder matrix.c to remove foward declaration and match split_common/matrix.c - fix logic from inherited from split_common * Add DIRECT_PINS documentation - review comments
