aspeed_wdt_config struct is used to store some HW configuration
information. Changing its naming to a more generic one,
aspeed_wdt_data, in order to contain more platform specific
inforamtion or SW callback functions.

I fail to see the point of this patch. It is just unnecessary churn.
Just like drivers should not be renamed because of an extended scope
or because someone doesn't like the old name, renaming variables should
be avoided as well. Such renames just make future bug fixes (which may
need to be backported) more difficult.
