We do not have any code to configure PMICs to sane defaults or to
defaults from the devicetree. I would surely appreciate if we would
get that code, but I am perfectly fine to put it into board code until
we are there.

How should runtime specific patching of the devicetree be done by the
devicetree?

Could be done, I am fine with leaving it in this patch.

For 'autoboot_timeout' I agree since there is no real point in putting
personal preference in there. 2s vs. 3s doesn't really justify putting
board specifics in. 'linux.bootargs.base' contains 'earlyprintk' which
should really be in a default environment as this can make a kernel non
bootable.
For 'nand' and 'boot.default' I would say that this is exactly the way
how a different default boot should be done, so I am fine with leaving
it in.

It's not silently changed, this goes down to a make savedefconfig which
removes all options which are set to default (or are selected by other
options).
