SoC: rt5682s: Disable jack detection interrupt during suspend 

The rt5682s driver switches its regmap to cache-only when the
device suspends and back to regular mode on resume. When the
jack detect interrupt fires rt5682s_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:

[   19.672162] rt5682s 2-001a: ASoC: error at soc_component_read_no_lock on rt5682s.2-001a 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.
