The driver depends on CONFIG_OF, so it is not necessary to use
CONFIG_OF and of_match_ptr here, so 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.

There are two mails with the same subject. Which one to consider?
This one is good (with commit message change
