Using int for cpu_{in, out}[bwl] is inconsistent with other part
because for address or value, uintN_t is used by other qemu part.
At least, softmmu, CPU{Read, Write}MemoryFunc, pci, target_phys_addr_t
and the callers of cpu_{in, out}[bwl]().
This patch removes the inconsistency.
IO port has its own address space so define pio_addr_t as uint32_t
because PCI io space width is 32bit.
And use uint{32, 16, 8}_t for ioport value.
Changing signedness of value might cause subtle issue. However
only a suspicious caller is kvm_handle_io() which is ok. And other callers
pass unsigned value in the first place.
