firmware: dmi: Add DMI_PRODUCT_FAMILY identification string
Sometimes it is more convenient to be able to match a whole family of products, like in case of bunch of Chromebooks based on Intel_Strago to apply a driver quirk instead of quirking each machine one-by-one. This adds support for DMI_PRODUCT_FAMILY identification string and also exports it to the userspace through sysfs attribute just like the existing ones.
