arm64: dts: imx8mm: add GPC node and power domains

This adds the DT nodes to describe the power domains available on the
i.MX8MM. Things are a bit more complex compared to other GPCv2 power
domain setups, as there is now a hierarchy of domains where complete
subsystems (HSIO, GPU, DISPLAY) can be gated as a whole, but also
fine granular gating within those subsystems is possible.

Note that this is still incomplete, as both VPU and DISP domains are
missing their reset clocks. Those aren't directly sourced from the CCM,
but have another level of clock gating in the BLKCTL of those domains,
which needs a separate driver.
