  Added the ability to specify the value of the shunt resistor in the
device tree instead of assuming it is 1 milliOhm.

Would be good to backport as well

Changes since v2:
- Remove newline
- Combined overflow fix with "Allow setting shunt resistor" commit
- Add description to "Add devicetree match table"
- Add fix for unhandled error case in ltc2945_value_store
- Use imperative in descriptions
- Remove unneeded overflow check from ltc2945_reg_to_val
- Fix up DIV_ROUND_CLOSEST_ULL calls, per docs divisor should be 32-bit
- Split one DIV_ROUND_CLOSEST_ULL change into separate commit per
 Guenter Roeck's comment
Changes since v1:
- Add devicetree match table
- Add kerneldoc for the ltc2945_data struct
- Cleanup excesive comments about the shunt resistor
- Switch to device_property_read_u32()
