You seem to be using a mutually exclusive set of ata(4) options and
devices (previously, this erroneously wasn't a bug). When including
options ATA_CAM you do _not_ want to also include any of the following
devices:
device		atapicam
device		atadisk
device		ataraid
device		atapicd
device		atapifd
device		atapist

Instead you need the corresponding driver from the following set:
device		scbus
device		ch
device		da
device		sa
device		cd
device		pass
