[ Upstream commit 8ca5104715cfd14254ea5aecc390ae583b707607 ]
Building with clang shows a variable that is only used by the
suspend/resume functions but defined outside of their #ifdef block:
sound/soc/ti/davinci-mcasp.c:48:12: error: variable 'context_regs' is not needed and will not be emitted
We commonly fix these by marking the PM functions as __maybe_unused,
but here that would grow the davinci_mcasp structure, so instead
add another #ifdef here.
Fixes: 1cc0c054f380 ("ASoC: davinci-mcasp: Convert the context save/restore to use array")
