[Description]
Returns a void pointer to a TIOS ROM call.

[Explanation]
_rom_call_addr returns a void pointer to a TIOS ROM call, which you can cast
to any other pointer type. After this cast, you can dereference it and handle
it like any other variable.

Note that <I>index</I> is the index of the ROM Call in hexadecimal form, but
without the <CODE>'0x'</CODE> prefix. The reason for this unusual convention is
that kernel programs use ROM calls by referring to <CODE>_ROM_CALL_xxx</CODE>,
where <I>xxx</I> is the hexadecimal index of the ROM call.

about the reason why _rom_call_addr_concat is used.
