x86: qemu: move x86 specific operations out of qfw core
The original implementation of qfw includes several x86 specific
operations, like directly calling outb/inb and using some inline
assembly code which prevents it being ported to other architectures.
This patch adds callback functions and moves those to arch/x86/
