The rest of the unmigrated CONFIG symbols in the CONFIG_SYS_NAND
namespace do not easily transition to Kconfig. In many cases they likely
should come from the device tree instead. Move these out of CONFIG
namespace and in to CFG namespace.

During compilation gcc throws warning:
drivers/mtd/nand/raw/fsl_elbc_nand.c: In function ‘fsl_elbc_nand_probe’:
drivers/mtd/nand/raw/fsl_elbc_nand.c:841:31: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
return fsl_elbc_chip_init(0, (void *)dev_read_addr(dev), dev);
^
Fix it by using dev_read_addr_ptr() function which returns pointer instead
of dev_read_addr() which returns integer type.

Subpage write support for freescale eLBC NAND controller driver is
implemented in U-Boot and was fixes in the commit d3963721d9 ("nand: Sync
with Linux v4.1").
So remove NAND_NO_SUBPAGE_WRITE flag from the fsl_elbc_nand.c driver. This
partially revert commit cb04c77234 ("nand/fsl: add NAND_NO_SUBPAGE_WRITE
to eLBC and IFC drivers"), only eLBC driver part.
With this change U-Boot with default settings can read from NAND UBIFS
image created on Linux with Linux default settings. Prior this change
U-Boot was unable to read from NAND UBIFS images created with Linux default
settings due to differnet UBI geometry.
Linux kernel fsl_elbc_nand.c driver also does not set NAND_NO_SUBPAGE_WRITE
flag and has implemented subpage write support.
Fixes: cb04c77234 ("nand/fsl: add NAND_NO_SUBPAGE_WRITE to eLBC and IFC drivers")

ecc.mode is set to 0 (aliased to NAND_ECC_NONE) either when function
nand_scan_ident() has not selected ecc.mode or when it selected it to none
ecc mode.
Distinguish between these two states by checking of node property
"nand-ecc-mode" which function nand_scan_ident() uses for filling ecc.mode.
This change fixes usage of none ecc mode if it is specified in DTS file.

For proper DM support it is required to fill also mtd->dev member.
Otherwise DM would not see nand device at all.

Initialize ECC configuration after nand_scan_ident() call and only in case
nand_scan_ident() have not done it. nand_scan_ident() fills ECC
configuration from device tree.
Fixes usage of NAND_ECC_SOFT_BCH when it is specified in device tree.

At present devres.h is included in all files that include dm.h but few
make use of it. Also this pulls in linux/compat which adds several more
headers. Drop the automatic inclusion and require files to include devres
themselves. This provides a good indication of which files use devres.

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.
