Bradley Morgan 109f733202 lib: Add two-byte cmpxchg emulation function
cmpxchg_emu_u8() emulates one-byte cmpxchg() in terms of four-byte
cmpxchg() for the architectures lacking native one-byte atomics.
The same architectures also lack native two-byte cmpxchg(), where
such an operation is not supported and either fails to compile via
BUILD_BUG() or fails to link, because the bad pointer sentinels
these architectures declare are never defined.

Add cmpxchg_emu_u16(), the two-byte sibling. It reads the enclosing
word with READ_ONCE(), splices the two target bytes through a union
and loops on cmpxchg() of the full word until the compare succeeds.
Like cmpxchg_emu_u8() it is fully ordered.

Unlike cmpxchg_emu_u8() it casts the old and new values to u16
internally and returns unsigned long, taking the old and new values
as unsigned long, per the suggestion from David Laight. The switch
statements in the architecture macros instantiate every size case,
so a cmpxchg() on a pointer type checks the two-byte case as well,
and a u16 parameter or return would make the macro casts and return
conversions warn there. With unsigned long parameters and return the
call sites need no narrowing casts, pointer exchanges compile warning
free, and the function still compares and returns exactly the 16 bits
the caller asked for, which matches the hardware cmpxchg r16
behaviour where a 16-bit compare only looks at the low 16 bits of
the register.

cmpxchg_emu_u8() keeps returning the old value unmasked, so a caller
that passes a wider old than 8 bits still gets it back as passed,
matching the behaviour the one-byte emulator always had.

The Kconfig symbol gating this file is renamed from
ARCH_NEED_CMPXCHG_1_EMU to ARCH_NEED_CMPXCHG_1_2_EMU, as it now
selects both the one-byte and the two-byte emulation.
