nand: mxc: Use appropriate page number in syndrome functions
The syndrome functions should use the page number passed as argument instead of
the page number saved upon NAND_CMD_READ0.
This does not make any difference if the NAND_NO_AUTOINCR option is set, but
otherwise this fixes accesses to the wrong pages.

nand: mxc: Prepare to add support for i.MX5
Add some abstraction to NFC definitions so that some parts of the current code
can also be used for future i.MX5 code.
Clean up a few things by the way.

mtd: nand: mxc_nand: Fix is_16bit_nand()
Currently is_16bit_nand() is a per SoC function and it decides the bus nand
width by reading some boot related registers.
This method works when NAND is the boot medium, but does not work if another
boot medium is used. For example: booting from a SD card and then using NAND
to store the environment variables, would lead to the following error:
NAND bus width 16 instead 8 bit
No NAND device found!!!
0 MiB
Use CONFIG_SYS_NAND_BUSWIDTH_16BIT symbol to decide the bus width.
If it is defined in the board file, then consider 16-bit NAND bus-width,
otherwise assume 8-bit NAND is used.
This also aligns with Documentation/devicetree/bindings/mtd/nand.txt, which
states:
nand-bus-width : 8 or 16 bus width if not present 8

omap_gpmc: add support for hw assisted BCH8
The kernel states:
---8<---
The OMAP3 GPMC hardware BCH engine computes remainder polynomials, it does not
provide automatic error location and correction: this step is implemented using
the BCH library.
--->8---
And we do so in u-boot.
This implementation uses the same layout for BCH8 but it is fix. The current
provided layout does only work with 64 Byte OOB.
