Introduce the properties in anticipation of QOM'ification; Q35 has the same

Note that we want to avoid a "ram size" property in the QOM interface since it
seems redundant to both properties introduced in this change. Thus the removal
of the ram_size parameter. We assume the invariant of both properties to sum up
to "ram size" which is already asserted in pc_memory_init(). Under Xen the
invariant seems to hold as well, so we now also check it there.

hw/pci-host/i440fx: Make MemoryRegion pointers accessible as properties

The goal is to eliminate i440fx_init() which is a legacy init function. This
neccessitates the memory regions to be properties, like in Q35, which will be
assigned in board code.

Since i440fx needs different PCI devices in Xen mode, and since i440fx shall
be self-contained, the PCI device will be created during realization of the
host. Thus the pointers need to be moved to the host structure to be usable as
properties.

32G (q35). To get the real user value, we need to get pci-host
passed property for default pci_hole64_size. Thus to get that,
create the qdev prior to memory init to better make estimations
on max used/phys addr.

This is in preparation to determine that host-phys-bits are
enough and also for pci-hole64-size to be considered to relocate
ram-above-4g to be at 1T (on AMD platforms).
