drm/amdkfd: Add cache line sizes to KFD topology

The KFD topology includes cache line size, but we have not been
filling that information out unless we are parsing a CRAT table.
Fill in this information for the devices where we have cache
information structs, and pipe this information to the topology
sysfs files.

v2: squash in fix from Joe (Alex)
