cxl/core: Rename bus.c to core.c
In preparation for more generic shared functionality across endpoint consumers of core cxl resources, and platform-firmware producers of those resources, rename bus.c to core.c. In addition to the central rendezvous for interleave coordination, the core will also define common routines like CXL register block mapping.
