drm/komeda: Add sysfs attribute: core_id and config_id
Add two sysfs node: core_id, config_id, user can read them to fetch the
HW product information.
Also, use memset to initialize config_id, rather than quirky C syntax.

[Merged Nathan's patch that uses memset to initialize config_id into
original patch as the fixes tag changed due to rebase, reworded the
commit to reference the merged patch]
