r336142:
ig4(4): add devmatch(8) PNP info

Now that we have all devices ids in a table add MODULE_PNP_INFO macro
to let devmatch autoload module

r336326:
Remove MODULE_PNP_INFO for ig4(4) driver

ig4(4) does not support suspend/resume but present on the hardware where
such functionality is critical, like laptops. Remove PNP info to avoid
breaking suspend/resume on the systems where ig4(4) load is not explicitly
requested by the user.
