Include thermal zones information in device tree for RK3588 variants.

This also enables the TSADC controller unconditionally on all boards
to ensure that thermal protections are in place via throttling and
emergency reset, once OPPs are added to enable CPU DVFS.

The default settings (using CRU as the emergency reset mechanism)
should work on all boards regardless of their wiring, as CRU resets
do not depend on any external components. Boards that have the TSHUT
signal wired to the reset line of the PMIC may opt to switch to GPIO
tshut mode instead (rockchip,hw-tshut-mode = <1>;)

It seems though that downstream kernels don't use that, even for
those boards where the wiring allows for GPIO based tshut, such as
