Max Filippov 583e6a5f55 target/xtensa: clean up unaligned access 
Xtensa cores may or may not have hardware support for unaligned memory
access. Remove TARGET_ALIGNED_ONLY=y from all xtensa configurations and
pass MO_ALIGN in memory access flags for all operations that would raise
an exception.
Simplify use of gen_load_store_alignment by passing access size and
alignment requirements in single parameter.
Drop condition from xtensa_cpu_do_unaligned_access and replace it with
assertion.
Add a test.
