Hello, as part of some spi-nand duties, I came to work with a TI AM62A
low-power starter kit. I initially could not use the spi controller and
tried to find a working-while-not-breaking-the-others fix but TBH I am
not getting all subtleties of this driver so I might very well be in the
wrong direction.

I then observed a massive throughput difference when using the DAC mode,
and disabling it really improved things, so I am proposing to bypass it
as well on this platform (and some few others which would also be
impacted by the change).

Let me know what you think.

Cheers,
Miquèl
