Our current goal is to get the buffers into the tty_port structure so
we can try and get rid of some of the locks entirely. We have lockless
kfifos and the port lifetime is the device lifetime plus so hopefully
it'll go away entirely eventually.

In the meantime I've no real opinion on the spin/raw_spin choices as
it's basically an RT question not a tty one so if the rt folks are
happy with it so am I.
