iop3xx: ATU and PCI memory configuration corrected
There are two 64 MB outbound memory windows at bus addresses 0x80000000..0x83ffffff and 0x84000000..0x87ffffff for PCI memory. Currently, on iop32x, only the lower window is available for allocations, limiting the available space to 64 MB. On iop33x the full 128 MB can be allocated, but the translation value is wrong for the upper window. The patch enables the full 128 MB space on iop32x and corrects the initialization of OMWTVR1. Redundant definitions are deleted. Tested using a Thecus N2100 board with a graphics adapter in the expansion slot. Both windows are in use: 00:05.0 VGA compatible controller: XGI Technology Inc.
