arm: Remove RISC OS personality

Browse Source 
The RISC OS personality seems to be unused and untested for a long time.
It is doubtful whether this personality worked ever as expected.
Let's rip it out.

Say Y here to include the kernel code necessary if you want to run
Acorn RISC OS/Arthur binaries under Linux. This code is still very
experimental; if this sounds frightening, say N and sleep in peace.
You can also say M here to compile this support as a module (which
will be called arthur).
