[PATCH] dt-bindings: timer: add #size-cells 2 for ARM

It's already widely used by dt-schemas, so I blindly assume it's correct.

Fixes warnings as:
arch/arm64/boot/dts/qcom/sdm845-oneplus-fajita.dt.yaml: timer@17c90000: #size-cells:0:0: 1 was expected
        From schema: Documentation/devicetree/bindings/timer/arm,arch_timer_mmio.yaml

FWIW, that makes sense to me, so:

I assume Rob will pick this (or otherwise correct me).

Thanks,

That's somewhat on purpose. There's no reason the timer needs >32-bits
of address or size. Sadly, QCom has ignored the warnings and just
copy-n-pasted the same thing over and over.
