Can we have it in a separate file like devicetree.[c|h] and
some stubs in the .h file for platforms that does not select
CONFIG_OF?

This:

+static int register_mappings(struct pinctrl_map const *maps, unsigned num_maps,
+                            bool dup, bool locked)

Instead of making this static, move the prototype to core.h and
use that from devicetree.c.

One rationale: the day after tomorrow we will have to get configs
from ACPI, UEFI and what not.

Apart from that I like the looks of this thing!
