riscv: dts: spacemit: Add thermal sensor for K1 SoC

Include the Thermal Sensor node in the SpacemiT K1 dtsi
with definitions for registers, clocks, and interrupts.
Additionally, configure thermal zones for the soc, package, gpu, and
clusters to enable temperature monitoring via the thermal framework.
