4.14-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit 66ec32fc7cd116dab5c02603ea8ec28ff92da3b5 ]
max17042_get_status uses the core power_supply_am_i_supplied. That function relies on DT properties to figure out the power supply topology, and will error out without DT.
Fixes max17042 battery status being reported as "unknown".
