Potential sleep mode issues

[masagrator]

Reposting sys-clk issue regarding the same portion of code, I recommend to either remove temperatures, move to GetTemperatureWithError (not tested if it solves issue, function is not available in libnx, you can find it in switchbrew wiki, works only with 17.0.0+) or move to i2c like I did with status monitor overlay.

I already migrated to i2c on my PR (heads up)
