Add vf610 reboot controller, which used to reboot whole system. Fix below
CHECK_DTB warnings:
arch/arm/boot/dts/nxp/vf/vf610-bk4.dtb: /soc/bus@40000000/src@4006e000:
failed to match any schema with compatible: ['fsl,vf610-src', 'syscon']
IC reference manual call it as system reset controller(SRC), but it is not
module as linux reset controller, which used to reset individual device.
SRC work as reboot controller, which reboot whole system. It provides a
syscon interface to syscon-reboot.

Change in v2
- change description to avoid confuse about reset controller.
- it is legacy device, more than 10 year. So try keep existed dts as it.
