This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.
Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

The most of drivers are using '_' instead of '-' in driver name. That's why
sync up these names to be aligned. It looks quite bad to see both in use.
It is visible via dm tree command.

Fixed wrong enumeration of nand_config structure. Added chip select
function before reading the nand chip for maf/dev id's, without this
unable to access id's from some of the micron chips. Also added a
print statement to identify if a nand flash is using on-die ecc.

Remove hardcoded base address of nand and replace it with the
value taken from device tree. Remove base address from header
file too.

This patch adds support for nand multi chip select.
Also adding CONFIG_SYS_NAND_MAX_CHIPS to Kconfig to specify maximum number
of nand chips.

Add support for disabling subpage write support via
CONFIG_SYS_NAND_NO_SUBPAGE_WRITE.
Currently the Linux Arasan driver does not support subpage writes and in
case of running UBI and accessing the same UBI volume from both U-Boot
and Linux it is required to have the same subpage write configuration
else the location of the UBI headers (EC + VID) will be misaligned
(subpage vs page) and incompatible. Hence the need for disabling
subpage write support in the U-Boot Arasan NAND driver.

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.
