[RFC PATCH-for-9.1 00/29] hw/i386/pc: Decouple ISA vs PCI-based machines

[Philippe Mathieu-Daudé]

Hi Igor,

This is the first steps to decouple the isapc VS q35/i440fx
machines. A new TYPE_PC_PCI_MACHINE is introduced to help
differentiating. Fields unrelated to the legacy isapc are
moved to the new PcPciMachineState structure.

More work remain in hw/i386/pc_piix.c so we can build a
binary with only CONFIG_ISAPC enabled.

Based-on: <20240327095124.73639-1-philmd@linaro.org>
