Subject: [PATCH 3/3] Define and use PCI_DEVICE_ID_MARVELL_88ALP01_CCIC for
	CAFÉ camera driver

Also, stop looking at the NAND controller (0x4100) and checking the
device class. For a while during development, all three functions on the
chip had the same ID. We made them fix that fairly promptly, and we can
forget about it now.
