From: Conor Dooley <conor.dooley@xxxxxxxxxxxxx>
The timers on the k210 have non standard interrupt configurations,
which leads to dtbs_check warnings:
k210_generic.dtb: timer@502d0000: interrupts: [[14], [15]] is too long
>From schema: Documentation/devicetree/bindings/timer/snps,dw-apb-timer.yaml
Split the timer nodes in two, so that the second timer in the IP block
can actually be accessed & in the process solve the dtbs_check warning.
