[PATCH v2 2/2] ASoC: rockchip: rockchip_sai: Fix runtime PM state after manual resume

[phucduc . bui]

From: bui duc phuc <phucduc.bui@xxxxxxxxx>

Probe manually resumes the device after pm_runtime_get_noresume().
Since the PM core is bypassed, runtime_status remains RPM_SUSPENDED even
though the hardware is active. A subsequent pm_runtime_put() therefore
skips runtime_suspend(), leaving the device permanently powered and
preventing autosuspend.

Fix this by calling pm_runtime_set_active() after the manual resume
succeeds, and defer pm_runtime_enable() until after the device has been
manually resumed and marked active. Also call pm_runtime_put_noidle()
on error to drop the usage count acquired by pm_runtime_get_noresume().
