[PATCHv3 14/32] x86: Adjust types used in port I/O helpers

["Kirill A. Shutemov" <kirill.shutemov@linux.intel.com>]

Change port I/O helpers to use u8/u16/u32 instead of unsigned
char/short/int for values. Use u16 instead of int for port number.

It aligns the helpers with implementation in boot stub in preparation
for consolidation.
