Subject: [PATCH] Remove unused LPSPI I/O helpers

Similar to the parent commit, these are prototyping leftovers from
f4a369e that beta clippy is picking up. However, I'm committing this
separately to make it easy to revert. I figured these could be helpful
for realizing EH1 traits, but I never tested them.
