mtd: move NAND files into a raw/ subdirectory
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.

- In current U-Boot flow using nand_init(), driver initialization

Above config is useful when NAND device's bus-width information cannot

- SPL boot does not support reading of ONFI parameters. This is done to

keep SPL code foot-print small.

- In current U-Boot flow using nand_init(), driver initialization

happens in board_nand_init() which is called before any device probe
|
||||
(nand_scan_ident + nand_scan_tail), thus device's ONFI parameters are

not available while configuring controller. So a static CONFIG_NAND_xx
