The code with this error was copy-pasted from Haswell. It was fixed with
commit dab81a4 (northbridge/intel/haswell: Fix copy paste error) for
Haswell. Do the same for Broadwell. Given that LP SKUs only support one
DIMM per channel, this change makes no difference in practice.

Create two new functions to fetch mrc_cache data (replacing
mrc_cache_get_current):
- mrc_cache_load_current: fetches the mrc_cache data and drops it into
the given buffer. This is useful for ARM platforms where the mmap
operation is very expensive.
- mrc_cache_mmap_leak: fetch the mrc_cache data and puts it into a
given buffer. This is useful for platforms where the mmap operation
is a no-op (like x86 platforms). As the name mentions, we are not
freeing the memory that we allocated with the mmap, so it is the
caller's responsibility to do so.
Additionally, we are replacing mrc_cache_latest with
mrc_cache_get_latest_slot_info, which does not check the validity of
the data when retrieving the current mrc_cache slot. This allows the
caller some flexibility in deciding where they want the mrc_cache data
stored (either in an mmaped region or at a given address).

Looks like no one really knows what this bit would be useful for, nor

on PCI *Express* bridges. Digging through git history, nearly all
instances of setting it on PCIe bridges comes from i82801gx, for which
no reason was given as to why this would be needed. The other instances
in Intel code seem to have been, unsurprisingly, copy-pasted.
Drop all uses of this definition and rename it to avoid confusion. The
negation in the name could trick people into setting this bit again.
