ASoC: rt712-sdca: fix for JD event handling in ClockStop Mode0

[ Upstream commit 7a8735c1551e489351172d0da96128f6f8b52b2d ]

When the system suspends, peripheral SDCA interrupts are disabled.
When system level resume is invoked, the peripheral SDCA interrupts
should be enabled to handle JD events.
Enable SDCA interrupts in resume sequence when ClockStop Mode0 is applied.
