Kumar Gala bf53ebf2c8 arch: convert to using newly introduced integer sized types
Convert code to use u{8,16,32,64}_t and s{8,16,32,64}_t instead of C99
integer types.  There are few places we dont convert over to the new
types because of compatiability with ext/HALs or for ease of transition
at this point.  Fixup a few of the PRI formatters so we build with newlib.
