No I think this is bootloader business, as is some PMU init -- states on
these signals impact power consumption at least.  It sounds right they
should be set to known state early.  2442 docs anyway show Port Data
levels are "undefined" at reset.

We can explicitly set them all again in kernel but it's likely best as
it is.
