broadwell: Compute channel disable masks at runtime
Introduce the `SPD_MEMORY_DOWN` macro to indicate that a slot is used
with memory-down. This enables computing the channel disable masks as
the bits for slots where the SPD address is zero. To preserve current
behavior, zero the SPD addresses for memory-down slots afterwards.
