cxl/port: Rename CXL_DECODER_{EXPANDER, ACCELERATOR} => {HOSTONLYMEM, DEVMEM}
In preparation for support for HDM-D and HDM-DB configuration
(device-memory, and device-memory with back-invalidate). Rename the current
type designators to use HOSTONLYMEM and DEVMEM as a suffix.
HDM-DB can be supported by devices that are not accelerators, so DEVMEM is
a more generic term for that case.
Fixup one location where this type value was open coded.
