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.

Additionally, this series contains couple of fixes, which can be applied
independently from the bd127x0 support patches. Fixes are:

Patch 2/9: Prevent read from uninitialized stack (found by Sashiko)
Patch 3/9: Prevent coefficient overflow with larget shunt resistor (found
	   by Sashiko)
Patch 4/9: Support module auto-loading when DT is used.

Revision history:
 v1 => v2:
  dt-bindings:
   - Fix compatible list as suggested by Krzysztof
  adm1275:
   - Add patches to fix issues pointed by Sashiko.
   - Add of_device_ids for all supported devices.
   - Add own switch 'case's for the new ICs instead of overloading
     existing ones
   - Drop i2c_device_id for bd12780a
   - Don't use IC-wildcard in macro name.
