Adds driver model support.
We need to be able to self initialize the NAND controller/chip
at probe and so enable CONFIG_SYS_NAND_SELF_INIT.
Doing so requires nand_register() API which is provided by nand.c
and needs to be enabled during SPL build via CONFIG_SPL_NAND_INIT.
But nand.c also provides nand_init() so we need to get rid of nand_init()
in omap_gpmc driver if CONFIG_SPL_NAND_INIT is set.

nand_bbt.c is not being built with the nand_base driver during SPL
build. This results in build failures if we try to access any nand_bbt
related functions.
Don't use any nand_bbt functions for SPL build.

The BCH detection hardware can generate ECC bytes for multiple
sectors in one go. Use that feature.
correct() only corrects one sector at a time so we need to call it
repeatedly for each sector.

This is always defined to 16K, so we move this over to
include/fsl_validate.h to start with. Next, we rename this from CONFIG_
to FSL_. Coalesce the various comments around this definition to be in
fsl_validate.h as well to explain the usage.

The patch prevents pages beyond the last from being unnecessarily read.
This occurs when the last page to be read is not the last page of the
last block. Before this change we would have read all the pages up to
the end of the last block.

Upstream linux commit 69fc01296c9281
commit a1286a1fc4 ("mtd: nand: Move Samsung specific init/detection
logic in nand_samsung.c") introduced a regression for Samsung SLC NAND
chips. Prior to this commit chip->bits_per_cell was initialized by calling
nand_get_bits_per_cell() before using nand_is_slc().
With the offending commit this call is skipped, leaving
chip->bits_per_cell cleared to zero when the manufacturer specific
'.detect' function calls nand_is_slc() which in turn interprets
bits_per_cell != 1 as indication for an MLC chip.
The effect is that e.g. a K9F1G08U0F NAND chip is falsely detected as
MLC NAND with 4KiB page size rather than SLC with 2KiB page size.
Add a call to nand_get_bits_per_cell() before calling the .detect hook
function in nand_manufacturer_detect(), so that the nand_is_slc()
calls in the manufacturer specific code will return correct results.

Rename omap_nand_read() to omap_nand_read_buf() to reflect
actual behaviour.
Use FIFO read address instead of raw read address for reads.
The GPMC automatically converts 32-bit/16-bit reads to NAND
device specific reads (8/16 bit). Use the largest possible
read granularity size for more efficient reads.
