Define a CXL Fixed Memory Window (CFMW).
Described in the CXL 2.0 ECN: CEDT CFMWS & QTG _DSM.
They are regions of Host Physical Addresses (HPA) on a system which
may be interleaved across one or more CXL host bridges. The system
software will assign particular devices into these windows and
configure the downstream Host-managed Device Memory (HDM) decoders
in root ports, switch ports and devices appropriately to meet the
interleave requirements before enabling the memory devices.
``targets.X=target`` provides the mapping to CXL host bridges
which may be identified by the id provied in the -device entry.
Multiple entries are needed to specify all the targets when
the fixed memory window represents interleaved memory. X is the
target index from 0.
``size=size`` sets the size of the CFMW. This must be a multiple of
256MiB. The region will be aligned to 256MiB but the location is
platform and configuration dependent.
``interleave-granularity=granularity`` sets the granularity of
