[PATCH v5 13/13] arm64: dts: imx8mq: Add node to G2 hardware

Split VPU node in two: one for G1 and one for G2 since they are
different hardware blocks.
Add syscon for hardware control block.
Remove reg-names property that is useless.
Each VPU node only need one interrupt.

version 5:
- use syscon instead of VPU reset
