Subject: [PATCH] MIPS: vpe-cmp: remove module owner pointer from struct class usage.

In commit 6e30a66433af ("driver core: class: remove struct module owner
out of struct class"), the module owner pointer was removed from struct
class, but this was missed for the mips vpe-cmp code due to lack of
build testing (and it being burried under a very unused config
settings.)  Fix this up by removing the module pointer to resolve the
build error.

Note, there are other problems with the driver model usage in this file
(static struct device usage, empty device release function, etc.), so it
probably could use some good cleaning up, but odds are this driver
really isn't used so hopefully it will just be removed entirely someday
soon as part of the general "remove unused arches" cleanup that is
slowly happening.
