irqchip/armada-370-xp: Use u32 type instead of unsigned long where possieble

For consistency across the driver, use the u32 type instead of unsigned
long for holding register values and return value of cpu_logical_map().

One exception is when the variable is referenced for passing into
for_each_set_bit(), in which case it has to be unsigned long.
