Commit Message

The SIE control block is huge and takes up too much space.

Additionally sie.h will now only contain sie lib structs and
declarations so we have a clear divide about which header contains
which things.

this is ok ^

the rest is a little confusing

maybe rephrase it to something like "split the hardware definitions
from sie.h into its own header, so that sie.h will only contain library
functions and structs"
