[PATCH v12 2/9] mfd: intel-lpss: add Dell Latitude 7275 to the resource conflict quirk

[Thierry Chatard]

From: "D. Manresa" <dmanresa@xxxxxxxxx>

The Dell Latitude 7275 2-in-1 has the same BIOS bug as the Latitude 5285:
the ACPI GEXP device declares an OperationRegion (BAR0) on the GNVS
variable SB04 and the I2C4 controller (INT3446) builds its _CRS from that
same variable, so intel_lpss_acpi fails to bind the controller with
-EBUSY and the front camera sensor (OV5670, INT3479) is never registered
unless acpi_enforce_resources=lax is passed.

Add the machine to the DMI table so QUIRK_IGNORE_RESOURCE_CONFLICTS is
applied to INT3446 on it as well.
