[PATCH 3/3] thermal: da9062/61: Prevent hardware access during system suspend

[Geert Uytterhoeven <geert+renesas@xxxxxxxxx>]

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")

Untested due to lack of hardware.
