soc/amd/{CZN,MDN,PCO}: Fix building with only single RW region

apu/amdfw_a was only getting added to CBFS when VBOOT_SLOTS_RW_AB was
selected, but needs to be added in the RW_A only case as well
(VBOOT_SLOTS_RW_A). Since VBOOT_SLOTS_RW_AB selects VBOOT_SLOTS_RW_A,
we can guard amdfw_a and _b separately and both will be added in the
RW_AB case.

TEST=build google/zork with VBOOT_SLOTS_RW_A or VBOOT_SLOTS_RW_AB
selected, ensure amdfw_a and amdfw_b are added to correct CBFS regions
as appropriate.
