[ARM] enable arbitary speed tty ioctls and split input/output speed
Add the ioctls and values needed for this to the ARM26/ARM32 ports. The
actual code has been in the base kernel for a while and automatically turns
on when a port sets the required defines.
[RMK: also added termbits.h changes to avoid build breakage]
