[PATCH 09/14] riscv: dts: canaan: add a specific compatible for k210's timers

From: Conor Dooley <conor.dooley at microchip.com>

The timers on the k210 have non standard interrupt configurations,
which leads to dtbs_check warnings:

k210_generic.dtb: timer at 502d0000: interrupts: [[14], [15]] is too long
>From schema: Documentation/devicetree/bindings/timer/snps,dw-apb-timer.yaml

Change to using the newly added canaan k210 specific binding to avoid
the warning.
