Subject: [PATCH] platform/x86/intel/hid: Add Dell Pro Rugged 10/12 tablet to VGBS DMI quirks

Dell Pro Rugged 10/12 tablets has a reliable VGBS method.
If VGBS is not called on boot, the on-screen keyboard won't appear if the
device is booted without a keyboard.

Call VGBS on boot on thess devices to get the initial state of
SW_TABLET_MODE in a reliable way.
