Gustavo RomeroandPeter Maydell 00936783ab target/arm: Enable FEAT_MEC in -cpu max 
Advertise FEAT_MEC in AA64MMFR3 ID register for the Arm64 cpu max as a
first step to fully support FEAT_MEC.

The FEAT_MEC is an extension to FEAT_RME that implements multiple
Memory Encryption Contexts (MEC) so the memory in a realm can be
encrypted and accessing it from the wrong encryption context is not
possible. An encryption context allow the selection of a memory
encryption engine.

At this point, no real memory encryption is supported, but software
stacks that rely on FEAT_MEC should work properly.

Jonathan CameronandPeter Maydell 9d8ade51a2 hw/arm/virt: Basic CXL enablement on pci_expander_bridge instances pxb-cxl 
Code based on i386/pc enablement.
The memory layout places space for 16 host bridge register regions after
the GIC_REDIST2 in the extended memmap. This is a hole in the current
map so adding them here has no impact on placement of other memory regions
(tested with enough CPUs for GIC_REDIST2 to be in use.)
The high memory map is GiB aligned so the hole is there whatever the
size of memory or device_memory below this point.

The CFMWs are placed above the extended memmap. Note the existing
variable highest_gpa is the highest GPA that has been allocated at
a particular point in setting up the memory map. Whilst this caused
some confusion in review there are existing comments explaining this
so nothing is added.

The cxl_devices_state.host_mr provides a small space in which to place
the individual host bridge register regions for whatever host bridges are
allocated via -device pxb-cxl on the command line. The existing dynamic
sysbus infrastructure is not reused because pxb-cxl is a PCI device not
a sysbus one but these registers are directly in the main memory map,
not the PCI address space.

Only create the CEDT table if cxl=on set for the machine. Default to off.
