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.
Change G2 assigned clock to match to the specifications.
In the both nodes all the clocks need to assigned to make
sure that control block will be correctly clocked even if
only one device node is enabled.

version 7:
- use nxp,imx8m-vpu-ctrl as phandle syscon property name
version 5:
- use syscon instead of VPU reset
