nand_spl: Fix cmd_ctrl usage in nand_boot.c.
When adding large page NAND support to this file, I had a misunderstanding
about the exact semantics of NAND_CTRL_CHANGE (which isn't documented
anywhere I can find) -- it is apparently just a hint to drivers,
which aren't required to preserve the old value for subsequent
non-"change" invocations.
This change makes nand_boot.c no longer assume this. Note that this
happened to work by chance with some NAND drivers, which don't preserve
the value, but treat 0 equivalently to NAND_CTRL_ALE.
I don't have hardware to test this, so any testing is appreciated.

nand_spl: read environment early, when booting from NAND using nand_spl
Currently, when booting from NAND using nand_spl, in the beginning the default
environment is used until later in boot process the dynamic environment is read
out. This way environment variables that must be interpreted early, like the
baudrate or "silent", cannot be modified dynamically and remain at their
default values. Fix this problem by reading out main and redundand (if used)
copies of the environment in the nand_spl code.

davinci_nand chipselect/init cleanup
Update chipselect handling in davinci_nand.c so that it can
handle 2 GByte chips the same way Linux does: as one device,
even though it has two halves with independent chip selects.
For such chips the "nand info" command reports:
Device 0: 2x nand0, sector size 128 KiB
Switch to use the default chipselect function unless the board
really needs its own. The logic for the Sonata board moves out
of the driver into board-specific code. (Which doesn't affect
current build breakage if its NAND support is enabled...)

davinci_nand: cleanup II (CONFIG_SYS_DAVINCI_BROKEN_ECC)
Remove CONFIG_SYS_DAVINCI_BROKEN_ECC option. It's not just nasty;
it's also unused by any current boards, and doesn't even match the
main U-Boot distributions from TI (which use soft ECC, or 4-bit ECC
on newer chips that support it).
DaVinci GIT kernels since 2.6.24, and mainline Linux since 2.6.30,
match non-BROKEN code paths for 1-bit HW ECC. The BROKEN code paths
do seem to partially match what MontaVista/TI kernels (4.0/2.6.10,
and 5.0/2.6.18) do ... but only for small pages. Large page support
is really broken (and it's unclear just what software it was trying
to match!), and the ECC layout was making three more bytes available
for use by filesystem (or whatever) code.
Since this option itself seems broken, remove it. Add a comment
about the MV/TI compat issue, and the most straightforward way to
address it (should someone really need to solve it).
