ASoC: rt5682: Disable jack detection interrupt during suspend 

The rt5682 driver switches its regmap to cache-only when the
device suspends and back to regular mode on resume. When the
jack detect interrupt fires rt5682_irq() schedules the jack
detect work. This can result in invalid reads from the regmap
in cache-only mode if the work runs before the device has
resumed:

[   56.245502] rt5682 9-001a: ASoC: error at soc_component_read_no_lock on rt5682.9-001a for register: [0x000000f0] -16

Disable the jack detection interrupt during suspend and
re-enable it on resume. The driver already schedules the
jack detection work on resume, so any state change during
suspend is still handled.

This is essentially the same as commit f7d00a9be1 ("SoC:
rt5682s: Disable jack detection interrupt during suspend")
for the rt5682s.
