xtensa: introduce spill_registers_kernel macro
commit e2fd1374c705abe4661df3fb6fadb3879c7c1846 upstream.
Most in-kernel users want registers spilled on the kernel stack and
don't require PS.EXCM to be set. That means that they don't need fixup
routine and could reuse regular window overflow mechanism for that,
which makes spill routine very simple.
