ARM i.MX: cleanup boot modes
...
The i.MX Processors support two different boot modes, the internal
boot mode and the external boot mode. Traditionally the external
NAND boot mode is handled in drivers/mtd/nand and the internal
boot mode is handled in arch/arm/mach-imx. This patch consolidates
the handling of both boot modes in arch/arm/mach-imx so that
the user does not have to look in the mtd kconfig section for
booting from NAND. Also, selecting between internal and external
boot mode now is a clear choice.
The external NAND boot mode has been independent of the mtd nand
driver, but as the code was contained in the NAND driver it was
not possible to support booting from NAND without a mtd nand driver.
This is changed with this patch.

imx nand: move initialization to preset function
...
This has two purposes. First we need to factor out initialization
to be able to do something different on v3 type controllers,
second with this patch we are independent of preinitialized register
values.

mxc_nand: fix correct_data function
...
The v2 controller has a totally different mechanism to check
whether the data we read had ecc errors or not. Implement this.
The mechanism in the v2 controller happens to be identical to
the v3 controller.

imx nand: add V1_V2 namespace to registers
...
This prepares the driver for v3 support. The v3 controller
has a completely different register layout, so add a V1_V2_
namespace to the register defines to avoid confusion with
the v3 regs.

imx_nand: make some internally used functions overwriteable

This patch prepares the driver to add v3 controller support
later. The v3 controller is basically the same controller as v1
and v2, but with a completely different register layout.

imx nand: remove unnecessary register write
...
NFC_SP_EN is cleared in probe and never set again, so we do not
need to clear it in other functions again.

imx_nand: rework get_dev_status
...
We save/restore the value in the buffer anyway, so it makes
no difference whether we use main_area0 or main_area1. So,
we can use main_area0 and remove main_area1 from the driver
which is otherwise unused. Also, clean up the comments in
get_dev_status.
