replace logical by bitand in pci_process_ISA_OF_ranges(), arch/powerpc/kernel/isa-bridge.c

replace logical by bit and for ISA_SPACE_MASK

in arch/powerpc/kernel/isa-bridge.c:
41:#define ISA_SPACE_MASK 0x1
42:#define ISA_SPACE_IO 0x1
...

83: if ((range->isa_addr.a_hi && ISA_SPACE_MASK) != ISA_SPACE_IO) {
...
89: if ((range->isa_addr.a_hi && ISA_SPACE_MASK) != ISA_SPACE_IO)

I think these should be single &'s, I can't test it (no hardware) please consider the patch below.
