[MTD] Nuke IVR leftovers
Support for the ITE8172 based boards was deleted a while ago so this is dead code. The Kconfig dependency on MIPS was wrong anyway, MIPS is a processor architecture and nothing else; guesses on systems architecture are likely to be wrong ...

2 * $Id: cstm_mips_ixx.c,v 1.14 2005/11/07 11:14:26 gleixner Exp $
3 *
4 * Mapping of a custom board with both AMD CFI and JEDEC flash in partitions.
5 * Config with both CFI and JEDEC device support.
6 *
7 * Basically physmap.c with the addition of partitions and
8 * an array of mapping info to accomodate more than one flash type per board.
