powerpc: Fix no interrupt handling in pata_of_platform
When no interrupt is specified the pata_of_platform fills the irq_res
resource with -1, which is wrong to do for two reasons:
1. By definition, 'no irq' should be IRQ 0, not some negative integer;
2. pata_platform checks for irq_res.start > 0, but since irq_res.start
is unsigned type, the check will be true for `-1'.
