Making serial code shared... #18

Interesting problem while making the serial code shared...

https://docs.rs/tm4c129x/0.7.0/tm4c129x/uart0/dr/struct._DATAW.html is safe. https://docs.rs/tm4c123x/0.7.0/tm4c123x/uart0/dr/struct._DATAW.html is unsafe.

I either get "need unsafe to call this function" or "unnecessary unsafe block".

Same with

https://docs.rs/tm4c123x/0.7.0/tm4c123x/uart0/ibrd/struct._DIVINTW.html and https://docs.rs/tm4c129x/0.7.0/tm4c129x/uart0/ibrd/struct._DIVINTW.html

Hmm, actually, it seems OK with the unsafe block regardless.
