This allows us to have some NAND specific stuff during registration,
like for example adding NAND specific device parameters.

It is not the chip, but this controller which cannot do subpage writes.
So, make sure we add the flag at the proper place, so it doesn't get
overwritten by flash detection anymore.

It could happen (1 out of 100 times) that NAND did not start up
correctly after warm rebooting, so barebox could not find its
environment or DMA timed out due to a stalled BCH. When resetting BCH
together with GPMI, the issue could not be observed anymore. We probably
need the consistent state already before sending commands to NAND.

Based on the U-Boot version. Changed to kernel style register layout, added
MX23 support (WIP!), made MMU aware and adapted to barebox.
