ARM: dts: rockchip: rename wdt nodename to watchdog on rv1108

A test with the command below gives for example this error:

/arch/arm/boot/dts/rv1108-evb.dt.yaml:
wdt@10360000: $nodename:0: 'wdt@10360000'
does not match '^watchdog(@.*|-[0-9a-f])?$'

Fix it by renaming the wdt nodename to watchdog
in the rv1108.dtsi file.

make ARCH=arm dtbs_check
DT_SCHEMA_FILES=Documentation/devicetree/bindings/watchdog/snps,dw-wdt.yaml
