ac94b7bcbe dm: syscon: Allow finding devices by driver data
We have a way to find a regmap by its syscon driver data value. Add the same
for syscon itself.

5725128507 dm: Add support for generic system controllers (syscon)
Many SoCs have a number of system controllers which are dealt with as a
group by a single driver. It is a pain to have to add lots of compatible
strings and/or separate drivers for each. Instead we can identify the
controllers by a number and request the address of the one we want.

Add a simple implementation of this which can be used by SoC driver code.
