Bernhard Beschow e052944a96 hw/pci/pci: Remove multifunction parameter from pci_create_simple_multifunction() 
There is also pci_create_simple() which creates non-multifunction PCI
devices. Accordingly the parameter is always set to true when a multi
function PCI device is to be created.

The reason for the parameter's existence seems to be that it is used in the
internal PCI code as well which is the only location where it gets set to
false. This one usage can be replaced by trivial code.

Remove this redundant, error-prone parameter.

* Calculate ram split, for memory below and above 4G. It's a bit

*
* - Traditional split is 3.5G (lowmem = 0xe0000000). This is the
* default value for max_ram_below_4g now.
*
* - Then, to gigabyte align the memory, we move the split to 3G
* (lowmem = 0xc0000000). But only in case we have to split in
* the first place, i.e. ram_size is larger than (traditional)
* lowmem. And for new machine types (gigabyte_align = true)
* only, for live migration compatibility reasons.
*
* - Next the max-ram-below-4g option was added, which allowed to
* reduce lowmem to a smaller value, to allow a larger PCI I/O
* window below 4G. qemu doesn't enforce gigabyte alignment here,
* but prints a warning.
*
* - Finally max-ram-below-4g got updated to also allow raising lowmem,
* so legacy non-PAE guests can get as much memory as possible in
* the 32bit address space below 4G.
*
* - Note that Xen has its own ram setup code in xen_ram_init(),
* called via xen_hvm_init_pc().
*
* Examples:
* qemu -M pc-1.7 -m 4G (old default) -> 3584M low, 512M high
* qemu -M pc -m 4G (new default) -> 3072M low, 1024M high
* qemu -M pc,max-ram-below-4g=2G -m 4G -> 2048M low, 2048M high
* qemu -M pc,max-ram-below-4g=4G -m 3968M -> 3968M low (=4G-128M)
