mtd: nand: pxa3xx_nand: add support for partial chunks

This commit is needed to properly support the 8-bits ECC configuration
with 4KB pages.

When pages larger than 2 KB are used on platforms using the PXA3xx
NAND controller, the reading/programming operations need to be split
in chunks of 2 KBs or less because the controller FIFO is limited to
about 2 KB (i.e a bit more than 2 KB to accommodate OOB data). Due to
this requirement, the data layout on NAND is a bit strange, with ECC
interleaved with data, at the end of each chunk.

When a 4-bits ECC configuration is used with 4 KB pages, the physical
data layout on the NAND looks like this:

| 2048 data | 32 spare | 30 ECC | 2048 data | 32 spare | 30 ECC |

So the data chunks have an equal size, 2080 bytes for each chunk,
which the driver supports properly.

When a 8-bits ECC configuration is used with 4KB pages, the physical
data layout on the NAND looks like this:

| 1024 data | 30 ECC | 1024 data | 30 ECC | 1024 data | 30 ECC | 1024 data | 30 ECC | 64 spare | 30 ECC |

So, the spare area is stored in its own chunk, which has a different
size than the other chunks. Since OOB is not used by UBIFS, the initial
implementation of the driver has chosen to not support reading this
additional "spare" chunk of data.

Unfortunately, Marvell has chosen to store the BBT signature in the
OOB area. Therefore, if the driver doesn't read this spare area, Linux
has no way of finding the BBT. It thinks there is no BBT, and rewrites
one, which U-Boot does not recognize, causing compatibility problems
between the bootloader and the kernel in terms of NAND usage.

To fix this, this commit implements the support for reading a partial
last chunk. This support is currently only useful for the case of 8
bits ECC with 4 KB pages, but it will be useful in the future to
enable other configurations such as 12 bits and 16 bits ECC with 4 KB
pages, or 8 bits ECC with 8 KB pages, etc. All those configurations
have a "last" chunk that doesn't have the same size as the other
chunks.

In order to implement reading of the last chunk, this commit:

 - Adds a number of new fields to the pxa3xx_nand_info to describe how
   many full chunks and how many chunks we have, the size of full
   chunks and partial chunks, both in terms of data area and spare
   area.

 - Fills in the step_chunk_size and step_spare_size variables to
   describe how much data and spare should be read/written for the
   current read/program step.

 - Reworks the state machine to accommodate doing the additional read
   or program step when a last partial chunk is used.

This commit is taken from Linux:

mtd: pxa3xx_nand: Fix initial controller configuration

The Data Flash Control Register (NDCR) contains two types
of parameters: those that are needed for device identification,
and those that can only be set after device identification.

Therefore, the driver can't set them all at once and instead
needs to configure the first group before nand_scan_ident()
and the second group later.

Let's split pxa3xx_nand_config in two halves, and set the
parameters that depend on the device geometry once this is known.

mtd: pxa3xx_nand: Increase the initial chunk size

The chunk size represents the size of the data chunks, which
is used by the controllers that allow to split transferred data.

However, the initial chunk size is used in a non-split way,
during device identification. Therefore, it must be large enough
for all the NAND commands issued during device identification.
This includes NAND_CMD_PARAM which was recently changed to
transfer up to 2048 bytes (for the redundant parameter pages).

Thus, the initial chunk size should be 2048 as well.

On Armada 370/XP platforms (NFCv2) booted without the keep-config
devicetree property, this commit fixes a timeout on the NAND_CMD_PARAM
command:
