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.

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.

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.

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.

NFC_SP_EN is cleared in probe and never set again, so we do not
need to clear it in other functions again.

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.

Add the offset to the register base instead. This is done
in preparation for v3 controller support.

This repairs a bug which came with patch "0cb00c1 omap nand: cleanup"
We first have to set ecc.layout before we can use it and should
do the nand_scan_tail after we set the ecc.mode.
