[Grantsdale] Graphics Device
del: device does not exist
Name: 82915G/P/GV/GL/PL/910GL [Grantsdale] Graphics Device
Note: 82915G/P/GV/GL/PL/910GL [Grantsdale] Graphics Device, since they obviously all share the same DEV-id; platform scheme over at https://de.wikipedia.org/wiki/Intel-900-Serie
It actually seems like the Grantsdale-class Graphics-Device headless suggested it to be already in 2004.
His suggested naming scheme also supports this, it's 82915x/xx for the Intel i915-ICH. Just like for the very next DEV-Id 2781h, which also belongs to the 900-Series ICH6 of the i915-chipset (Codename Grantsdale).
While the next Dev-Id is 2781 and reads "82915G Integrated Graphics Controller", i'd suggest naming it "82915G/P/GV/GL/PL/910GL [Grantsdale] Graphics Device"

The P-variants don't have any graphics, so I have removed them from the list.
(Also, usually the LPC device identifies the exact chipset, so 82915 Series would suffice as well, but I'll just keep it this way to avoid changing all other 82915 entries.)
