parisc: add u16 support to cmpxchg()
Add (and export) __cmpxchg_u16(), teach __cmpxchg() to use it.
And get rid of manual truncation down to u8, etc. in there - the
only reason for those is to avoid bogus warnings about constant
truncation from sparse, and those are easy to avoid by turning
that switch into conditional expression.
