106e0121e2 thermal/drivers/bcm2711: Don't clamp temperature at zero 
The thermal sensor on BCM2711 is capable of negative temperatures, so don't
clamp the measurements at zero. Since this was the only use for variable t,
drop it.

This change based on a patch by Dom Cobley, who also tested the fix.

This adds the thermal sensor driver for the Broadcom BCM2711 SoC,
which is placed on the Raspberry Pi 4. The driver only provides
SoC temperature reading so far.
