mtd: spinand: Use the spi-mem dirmap API
Make use of the spi-mem direct mapping API to let advanced controllers
optimize read/write operations when they support direct mapping.
Based on a linux commit 981d1aa0697c ("mtd: spinand: Use the spi-mem dirmap API")
created by Boris Brezillon <[email protected]> with additional
fixes taken from Linux 6.10.
