Support ROHM BD12780(A) and BD12790

The BD12780 and BD12780A hot-swap controllers are very similar to Analog
Devices ADM1278. There are only some minor differences in the registers.

The BD12790 is largely similar to the ADM1272, with slightly different
coefficients and minor register changes.

This series adds basic support for these ROHM ICs.

The last patch adds of_device_id table with entries for the newly added
controllers. This fixes the module auto-load on the test board with old
Debian user-space.

I have no idea if adding the of_device_id -entries for other ICs could
cause problems in some existing systems. Hence only new ICs were added
to the of_device_id tables.
