dmi: extend dmi_get_year() to dmi_get_date()
There are cases where full date information is required instead of just the year. Add month and day parsing to dmi_get_year() and rename it to dmi_get_date(). As the original function only required '/' followed by any number of parseable characters at the end of the string, keep that behavior to avoid upsetting existing users. The new function takes dates of format [mm[/dd]]/yy[yy]. Year, month and date are checked to be in the ranges of [1-9999], [1-12] and [1-31] respectively and any invalid or out-of-range component is returned as zero. The dummy implementation is updated accordingly but the return value is updated to indicate field not found which is consistent with how other dummy functions behave.
