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 0434d3f4525a ("mailbox/omap: Handle if CONFIG_PM is disabled")
This commit fixes commit cab04ab5900f ("ASoC: fsl_asrc: Don't use devm_regmap_init_mmio_clk") commit 203773e39347 ("ASoC: fsl_esai: Don't use devm_regmap_init_mmio_clk") commit 2277e7e36b4b ("ASoC: fsl_sai: Don't use devm_regmap_init_mmio_clk")
