Subject: [PATCH 4/8] arm: make asm/ioctls.h mostly generic

This makes the arm version of asm/ioctls.h almost
identical to the asm-generic version, the only
difference being the definition of FIOQSIZE.

The only user-visible change is the addition of
the TCGETX/TCSETX/TCSETXF/TCSETXW ioctl family,
which was not defined on ARM previously.
