[PATCH qemu v5 4/7] hw/cxl: Update CXL Fixed Memory Window ACPI description to include Back Invalidate support.

[Jonathan Cameron <Jonathan.Cameron@huawei.com>]

Defaults for these windows has always been to enable anything QEMU supports.
With the addition of back invalidate support it is necessary to specify that
host windows support this.

CXL emulation is currently only suitable for software stack verification.
The relaxation of the restrictions on this window to include BI have no
affect on the OS until BI capable devices are added and until now these
have not existed. As such no backwards compatibility impacts are expected
from this change.

v5: Equivalent of the default change in the window restrictions patch.
    That patch isn't ready for upstream just yet, so for now just
    change the value for everyone.
