[RFC PATCH v2 01/28] cxl: Rename CXL_MEM to CXL_PCI

[Ben Widawsky <ben.widawsky@intel.com>]

With the upcoming introduction of a driver to control the non-PCI
aspects of CXL.mem, such as interleave set creation and configuration,
there will be an opportunity to disconnection control over CXL device
memory and CXL device manageability. CXL device manageability is
implemented by the cxl_pci driver. Doing this rename allows the CXL
memory driver to be enabled by a new config option independently of CXL
device manageability through CXL.io/PCI mechanisms.
