That's a const... but also I don't get the need for select.

This looks unusual. Basically you change the bindings, because before
they required "arm,pl353-smc-r2p1", "arm,primecell".
Don't you want here items:
- const: ...
- const: ...

Just maxItems. Description is obvious.

Isn't apb_pclk the bus clock (so second item below)?

Match with start ^. I think you cannot have 9 nodes and hex can appear
in address so maybe:
"^.*@[0-3],[a-f0-9]+$":
