Unlike the CPU, the CDSP/Modem does not throttle its speed automatically when it reaches high temperatures in kodiak.
Set up CDSP cooling by throttling the cdsp when it reaches 100°C and for modem when it reaches to 95°C. Add polling-delay-passive so the governor periodically evaluates the zone during passive cooling and steps up cooling levels when temperature stabilizes below the next trip. Since the remoteproc_mpss node doesn't exist on non modem boards, the cooling-maps that reference it cause DT compilation errors. To fix that remove inherited mdmss cooling-map nodes.
