[Qemu-block] [PATCH 3/4] hw/i386/pc_sysfw: Let pc_system_firmware_init() access PCMachineState

[Philippe Mathieu-Daudé]

PCMachineState will be used in the next patch.
Since We can access PCMachineClass from it, directly use it.
We can also access pcmc->pci_enabled, remove the isapc_ram_fw
argument.
