Certain clocks on the RK3576 are additionally essentially "gated" behind
some bit toggles in the IOC GRF range. Downstream ungates these by
adding a separate clock driver that maps over the GRF range and leaks
their implementation of this into the DT.
Instead, define some new clock IDs for these, so that consumers of these
types of clocks can properly articulate which clock they're using, so
that we can then add them to the clock driver for SoCs that need them.

Mainline Linux uses different clock IDs from both downstream and
mainline TF-A, which both got them from downstream Linux. If we want to
control clocks through SCMI, we'll need to know about these IDs.
Add the relevant ones prefixed with SCMI_ to the header.

Block comments should align the * on each line, as checkpatch rightfully
pointed out, so fix that style issue on the newly added rk3576 headers.

Add clock and reset ID defines for rk3576.
Compared to the downstream bindings written by Elaine, this uses
continous gapless IDs starting at 0. Thus all numbers are
different between downstream and upstream, but names are kept
exactly the same.
Also add documentation for the rk3576 CRU core.
