[ARM] 3223/1: remove ixdp2x01 cs89x0 hack
Patch from Lennert Buytenhek Remove the ixdp2x01 cs89x0 hack from ixp2000's io implementation. Since the cs89x0 driver has been made properly aware of the odd way the cs89x0 is hooked up on the ixdp2x01, we don't need this hack anymore.

135/*
136 * This is an ugly hack but the CS8900 on the 2x01's does not sit in any sort
137 * of "I/O space" and is just direct mapped into a 32-bit-only addressable
138 * bus. The address space for this bus is such that we can't really easily
139 * make it contiguous to the PCI I/O address range, and it also does not
140 * need swapping like PCI addresses do (IXDP2x01 is a BE platform).
141 * B/C of this we can't use the standard in/out functions and need to
142 * runtime check if the incoming address is a PCI address or for
143 * the CS89x0.
