[PATCH v4 11/11] arm64: dts: imx8mq: Add node to G2 hardware

[Benjamin Gaignard <benjamin.gaignard@collabora.com>]

Split VPU node in two: one for G1 and one for G2 since they are
different hardware blocks.

Signed-off-by: Benjamin Gaignard <benjamin.gaignard@collabora.com>

version 4:
- rebase the change on top of VPU reset patches:
  https://www.spinics.net/lists/arm-kernel/msg878440.html

version 2:
- remove useless clocks in VPUs nodes
