ASoC: fsl_asrc fsl_esai fsl_sai: allow CONFIG_PM=N

[ Upstream commit 6a56433 ]

When CONFIG_PM=N, pm_runtime_put_sync() returns -ENOSYS
which breaks the probe function of these drivers.

Other users of pm_runtime_put_sync() typically don't check
the return value. In order to keep the program flow as
intended, check for -ENOSYS.

This commit is similar to commit 0434d3f (omap-mailbox.c).
