It could be, but pc87312/smc37c669/vt82c686 inherit of TYPE_ISA_SUPERIO
so would require something like:

common-obj-$(call land,$(CONFIG_ISA_SUPERIO),$(CONFIG_PC87312)) \
            += pc87312.o
common-obj-$(call land,$(CONFIG_ISA_SUPERIO),$(CONFIG_VT82C686)) \
            += vt82c686.o
common-obj-$(call land,$(CONFIG_ISA_SUPERIO),$(CONFIG_SMC37C669)) \
            += smc37c669-superio.o
