Make CONFIG_SYS_NAND_U_BOOT_OFFS configurable through Kconfig, just like
SYS_NAND_BUSWIDTH_16BIT this is only enabled on some SoCs using depends,
to avoid double defining it for SoCs which have not yet moved to Kconfig
for this.

Having this in Kconfig is useful because this is something which may
differ from one board to the other even when using the same SoC.

We only ever use syndrome mode for the partitions which contain the SPL,
as that is required for the BROM to be able to read the SPL.

Instead of using some arbritray limit for deciding whether or not to
use syndrome, be smart and check if u-boot-dtb.bin is directly behind
the SPL, if it is not then it is on its own partition and we should not
use syndrome.

Note the reason why we only use syndrome mode for the SPL is because it
comeswith weaker randomization, introducing a risk for more bit errors,
so we want to avoid it when possible.

We eventually want to add full nand support, since it makes no sense
to build SPL with nand support and u-boot without, or the other way
around, a single option will suffice.

Renaming the Kconfig option now makes things easier when we add full
nand support in the future.

The "obj-$(CONFIG_NAND_SUNXI) += sunxi_nand_spl.o" is moved to an
"ifdef CONFIG_SPL_BUILD" block in the Makefile.

The BROM does not care / use bad page markings, instead it deals with
any bad pages in the first erase-block by simply trying to load "boot0"
from the next erase-block.

This commit implements the same strategy for the sunxi spl nand code,
allowing it to boot from the backup boot partition when the main boot
partition is bad (tested by erasing the main boot partition).

Auto detect the nand configuration parameters, like the BROM does.

This allows us to get rid of various Kconfig settings, and is
necessary to support generic boards like the mk802 which have seen
many production runs with different nands.

The full blown u-boot/kernel nand driver uses the nand id to determine
this info, for the SPL we do as the BROM does and simply try a few
standard configs.

Note the table only contains configs which are known to actually be used,
rather then all the configs the BROM tries. This means that it may need
to be updated in the future as we add support for nand on more boards.

it was not muxed this way. GPC7 is a standard NAND pin, so it should

In syndrome mode we set the NFC_SEQ bit in the command register, so the
spare-area register is not used. Also the value currently being written is
actual wrong, the ecc sits at "column + CONFIG_NAND_SUNXI_SPL_ECC_PAGE_SIZE"
not just CONFIG_NAND_SUNXI_SPL_ECC_PAGE_SIZE.

nand_spl_load_image() always gets called with either CONFIG_SYS_TEXT_BASE
or spl_image.load_addr as destination, both of which are properly aligened,
and have plenty of space for "overshooting" up to
CONFIG_NAND_SUNXI_SPL_ECC_PAGE_SIZE bytes, as we read in
CONFIG_NAND_SUNXI_SPL_ECC_PAGE_SIZE bytes chunks.

This saves CONFIG_NAND_SUNXI_SPL_ECC_PAGE_SIZE (typically 1k) in
SPL size, which is a lot on the total 24k we have.

Note this changes the dma destination from SRAM to DRAM, so this patch
updates the DDMA_DST_TYPE bits in the dma controller cfg0 reg accordingly.

With the unified / cleaned up default display output selection changes,
which were done as part of adding composite video out support, our
example LCD_MODE line in the A13-OLinuxIno defconfigs causes the display
code to setup a LCD console by default, rather then a VGA console.

Given that the LCD console is only useful for people who have hooked up
the exact lcd-panel from the config, while most people will not have any
lcd panel connected to these boards, this is not a good default.

Dropping the LCD_MODE line which was intended as an example fixes this,
instead add a link to the LCD_MODE help text pointing to
http://linux-sunxi.org/LCD which contains the removed and other example
modes.

They compile drivers/mtd/nand/denali_spl.c and it has a page_buffer

This buffer required 8KB in .bss section before that commit and now
it has been increased to 16KB.  Given limited code/memory size for SPL,
it is not a good idea to allocate a page buffer statically.  In the
