mb/qemu-{i440fx,q35}: Use POSTCAR stage to load the ramstage
Qemu does not have a real CAR but postcar stage is still useful
for testing the stage.
The postcar stage is also mandatory for x86_64 to setup
pagetables for x86_64 ramstage.
Do not set up MTRRs, as qemu ignores them anyways.
Tested on qemu-i440fx and qemu-q35.
