[PATCH] power: supply: cw2015: use dev_err_probe to allow deferred probe

[Peter Robinson]

Deal with deferred probe using dev_err_probe so the error is handled
and avoid logging lots probe defer information like the following:

[    9.125121] cw2015 4-0062: Failed to register power supply
[    9.211131] cw2015 4-0062: Failed to register power supply

Fixes: b4c7715c10c1 ("power: supply: add CellWise cw2015 fuel gauge driver")
