ipq807x: add critical thermal trips to all thermal zones

Browse Source 
Kernel 6.1 has started actually enforcing the bindings requirment that
thermal zones must have associated trips described as well, otherwise they
will fail during probing with:
[    0.865494] thermal_sys: Failed to find 'trips' node
[    0.867254] thermal_sys: Failed to find trip points for thermal-sensor id=4
[    0.872271] thermal_sys: Failed to find 'trips' node
[    0.878898] thermal_sys: Failed to find trip points for thermal-sensor id=5

[    0.902668] thermal_sys: Failed to find trip points for thermal-sensor id=7
[    0.907964] thermal_sys: Failed to find 'trips' node
[    0.914569] thermal_sys: Failed to find trip points for thermal-sensor id=8
[    0.921203] thermal_sys: Failed to find 'trips' node
[    0.926469] thermal_sys: Failed to find trip points for thermal-sensor id=14
[    0.931759] thermal_sys: Failed to find 'trips' node
[    0.938703] thermal_sys: Failed to find trip points for thermal-sensor id=15

So, since CPUFreq support isnt yet upstream we can start by adding critical
trips to all of the thermal zones to protect the devices against severely
overheating.
Qualcomm has set the overheat trip at 120 C but lets be conservative and
set it at 110 C.

This patch has been sent upstream as well.

Subject: [PATCH] arm64: dts: qcom: ipq8074: add critical thermal trips
According to bindings, thermal zones must have associated trips as well.
Since we currently dont have CPUFreq support and thus no passive cooling
lets start by defining critical trips to protect the devices against
severe overheating.
