machine: query kernel-irqchip property

Browse source 
Running
    x86_64-softmmu/qemu-system-x86_64 -machine pc,kernel_irqchip=on -enable-kvm
leads to crash:
    qemu-system-x86_64: qemu/util/qemu-option.c:387: qemu_opt_get_bool_helper:
    Assertion `opt->desc && opt->desc->type == QEMU_OPT_BOOL' failed.  Aborted
    (core dumped)

This happens because the commit e79d5a6 ("machine: remove qemu_machine_opts
global list") removed the global option descriptions and moved them to
MachineState's QOM properties.

Fix this by querying machine properties through designated wrappers.
