Subject: [PATCH 3/3] media: ipu-bridge: Add DMI quirk for Dell 14 laptops with
 upside down sensors

The Dell 14 PA14260 has upside down issue by mechanical design.
There are 4 modules desing into this product. But only two modules has
this upside down issue. We cannot use sensor HID, only can use module
ID to distinguish the product.
The rotation value should be reported by 180 degree by module ID.
