cxl: Rename CXL_MEM to CXL_PCI
The cxl_mem module was renamed cxl_pci in commit 21e9f76733a8 ("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.
