Use le types in all non-legacy places.

Emphasize that legacy endian was different, but change all the basic types
to use le32 etc as a constant reminder.

Thorough endianness notes for legacy.

This is noted at the beginning of the spec, but let's make it explicit
everywhere le32 etc is used.

Remove __ annotations on pci.

We use le32 etc elsewhere, make it consistent.

CCW: Make it very clear that CCW channel commands are big-endian.

Noone is likely to get confused, but let's be explicit since the rest of
the spec is little-endian.
