rtc: pm8xxx: fixup checkpatch/style issues

This patchset is based on Stephen Boyd's PM8921 modernization/cleanups
(http://lkml.kernel.org/g/1393441166-32692-1-git-send-email-sboyd@codeaurora.org),
and allows for this RTC driver to be usable again.

This patch (of 6):

Before performing additional cleanups to this driver, do the easy cleanups
first.
