This is v2 of a patch series that adds support for DM to the MPC8XXX SPI
driver, cleans up the driver code, fixes a few minor problems.

Some TODOs are left over for later, such as proper SPI speed setting,
and support for SPI mode setting. These would be enhancements to the
original functionality, and can come later.

The legacy functionality is removed in this version, so old boards in
the tree might end up with broken SPI functionality.

Boards with
- configs/MPC8349EMDS_defconfig
- configs/ids8313_defconfig

Can you convert this boards to use DM_SPI, we have build issue[2]

Heiko, if you agree, I'd say we disable the SPI support for this board for now (and possibly permanently), since really supporting the SPI multiplexer would entail writing a DM driver for it, which would entail creating a SPI mux uclass, and similar inconveniences (and I think putting that much work in a board that old is at least dubious). As far as I can tell, this is the only board with the multiplexer mechanism.

I have two more larger conversion series in my queue, which will hopefully make it easier to convert the MPC83xx boards to DM (including SPI), but since I'm busy working on non-U-Boot-related things right now, I won't be able to finalize the first this week; hopefully next week.
