mfd: intel-lpss: Add resource conflict quirk for Dell Latitude 5285
The Dell Latitude 5285 2-in-1 has a BIOS bug where the ACPI GEXP device
and the I2C4 controller (INT3446) both claim the same MMIO region via the
shared SB04 variable. This causes intel_lpss_acpi to fail binding to I2C4
with -EBUSY, preventing the front camera (OV5670) sensor from being
registered.
Match the affected machine by DMI and the affected device by ACPI ID,
carrying QUIRK_IGNORE_RESOURCE_CONFLICTS in the ACPI match data and
applying it to the per-device info in probe. This follows the quirk
organisation used by the PCI counterpart.
