[PATCH 2/4] drivers/clocksource/moxart: Refactor enable/disable

[Joel Stanley]

Hi Daniel,

Here's a commit message for this patch. If you'd prefer me to resend
the entire series with this included then I can do that.

This patch abstracts the enable and disable register writes into their
own functions in preparation for future changes to use SoC specific
values for the writes.
