[PULL 1/4] microvm: use 3G split unconditionally

[Gerd Hoffmann]

Looks like the logic was copied over from q35.

q35 does this for backward compatibility, there is no reason to do this
on microvm though.  Also microvm doesn't need much mmio space, 1G is
more than enough.  Using an mmio window smaller than 1G is bad for
gigabyte alignment and hugepages though.  So split @ 3G unconditionally.

[PULL 2/4] microvm: drop max-ram-below-4g support

[Gerd Hoffmann]

Not useful for microvm and allows users to shoot themself
into the foot (make ram + mmio overlap).

[PULL 3/4] x86: move max-ram-below-4g to pc

[Gerd Hoffmann]

Move from X86MachineClass to PCMachineClass so it disappears
from microvm machine type property list.
