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.
