[PATCH] media: i2c: cvs: Add Lattice device quirk for VID:0x2ac1 PID:0x20d1

[Kate Hsuan]

On Dell laptops such as the XPS 14 (DA14250), the IPU6 camera fails to
initialize due to a missing device quirk for the Lattice device. The
kernel logs the following error during probe:

[  7.299665] intel_cvs i2c-INTC10E0:00: No quirks for device (VID:0x2ac1 PID:0x20d1)
[  7.299976] intel_cvs i2c-INTC10E0:00: error -EREMOTEIO: get caps failed
[  7.300026] intel_cvs i2c-INTC10E0:00: probe with driver intel_cvs failed with error -121

Add a matching quirk entry for VID 0x2ac1 and PID 0x20d1 to allow
intel_cvs to configure the device properly and enable the camera.
