[PATCH -next v2] gpio: max3191x: remove redundant of_match_ptr()

[Zhu Wang <wangzhu9@xxxxxxxxxx>]

The driver depends on CONFIG_OF, so it is not necessary to use CONFIG_OF
and of_match_ptr() here, we remove them all.

Even for drivers that do not depend on CONFIG_OF, it's almost always
better to leave out the of_match_ptr(), since the only thing it can
possibly do is to save a few bytes of .text if a driver can be used both
with and without it.
