Subject: [PATCH] dt-bindings: uniphier-thermal: add minItems to socionext,tmod-calibration

As the description says, this property contains a pair of calibration
values. The number of items must be exactly 2.

Add minItems to check a too short property.

While I was here, I also added this property to the example because
this is the case in the real DT file,
arch/arm64/boot/dts/socionext/uniphier-ld20.dtsi

Also, fix the interrupt type (edge -> level) to align with the
real DT.
