tty: Keep the default buffering to sub-page units
We allocate during interrupts so while our buffering is normally diced up
small anyway on some hardware at speed we can pressure the VM excessively
for page pairs. We don't really need big buffers to be linear so don't try
so hard.
In order to make this work well we will tidy up excess callers to request_room,
which cannot itself enforce this break up.
