[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]
