thermal: da9062/61: Prevent hardware access during system suspend
[ Upstream commit 760eea43f8c6d48684f1f34b8a02fddc1456e849 ]
The workqueue used for monitoring the hardware may run while the device
is already suspended. Fix this by using the freezable system workqueue
instead, cfr. commit 51e20d0e3a60cf46 ("thermal: Prevent polling from
happening during system suspend").
Fixes: 608567aac3206ae8 ("thermal: da9062/61: Thermal junction temperature monitoring driver")
