[U-Boot] [PATCH v6 09/27] mtd: move NAND files into a raw/ subdirectory

[Miquel Raynal <miquel.raynal@bootlin.com>]

NAND flavors, like serial and parallel, have a lot in common and would
benefit to share code. Let's move raw (parallel) NAND specific code in a
raw/ subdirectory, to ease the addition of a core file in nand/ and the
introduction of a spi/ subdirectory specific to SPI NANDs.

Documentation, README*, and MAINTAINERS files are updated accordingly.
