cxl: Rename CXL_MEM to CXL_PCI

Browse Source 
The cxl_mem module was renamed cxl_pci in commit 21e9f76733 ("cxl:
Rename mem to pci"). In preparation for adding an ancillary driver for
cxl_memdev devices (registered on the cxl bus by cxl_pci), go ahead and
rename CONFIG_CXL_MEM to CONFIG_CXL_PCI. Free up the CXL_MEM name for
that new driver to manage CXL.mem endpoint operations.

The CXL.mem protocol allows a device to act as a provider of
"System RAM" and/or "Persistent Memory" that is fully coherent
as if the memory was attached to the typical CPU memory
controller.
The CXL specification defines a "CXL memory device" sub-class in the
PCI "memory controller" base class of devices. Device's identified by
this class code provide support for volatile and / or persistent
memory to be mapped into the system address map (Host-managed Device
Memory (HDM)).
Say 'y/m' to enable a driver that will attach to CXL.mem devices for
configuration and management primarily via the mailbox interface. See
Chapter 2.3 Type 3 CXL Device in the CXL 2.0 specification for more
details.
