parport_pc: it887x fix
The IO port range requested by parport_pc.c:sio_ite_8872_probe is too small.
The IO-ports of ttyS1 (0x2f8) will be missconfigured by the ITE-chip. The ITE
starts looking for the chip a 0x2a0. An IO-portrange of 32 will not overwrite
the ports of ttyS1. Therefore register 0x60 should be written with
0xe5000000, enabling the ITE and setting IO-portsize to 32 bytes.
