pc: Save size of RAM below 4GB

The ram_below_4g value will be useful in other places, such as the ACPI

piix: fix 32bit pci hole

Make the 32bit pci hole start at end of ram, so all possible address
space is covered.

We used to try and make addresses aligned so they are easier to cover
with MTRRs, but since they are cosmetic on KVM, this is probably not
worth worrying about....

On q35, IRQ2/8 can be reserved for hpet timer 0/1. And pin 16~23
can be assigned to hpet as guest chooses. So we introduce intcap...

With a help of negative memory region priority PCI address space
