The max8903_charger.h file indicated that dcm and dok were not optional
when dc_valid is set.
It makes sense to have dok as a compulsory pin when dc_valid is given.
However dcm can be optionally wired to a fixed level especially when the
circuit is configured for dc power exclusively.
The previous implementation already allowed for this somewhat, however no
error was given if dok wasn't given whilst dc_valid was.
The new implementation enforces dok presence when dc_valid is given. Whilst
allowing dcm to be optional.

Just found one nit. Don't split the strings.
dev_err(dev,
"When DC is wired, DOK should be wired as well.\n");
I saw that one as well when I ran checkpatch, however I thought if I
changed it then I would get a warning about the line being > 80 chars.
So wasn't sure which direction to go.
Thanks
Chris
