CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

We only care about if there is any successful match from the dmi table
or no match at all, we can make dmi_check_system return immediately if
we have a successful match instead of iterate thorough the whole table.
