It makes sense to advertise this configuration to the guest firmware via an easy to parse fw_cfg file (ACPI is too complex for firmware to parse), and indeed PIIX4 does that. However, since acpi_pm1_cnt_init() is not specific to PIIX4, neither should be the fw_cfg file. This patch makes "etc/system-states" appear on all chipsets modified in the previous patch, not just PIIX4 (assuming they have fw_cfg at all).

Remove the parameter from the prototype, and update callers. As a result, the pc_init1() function no longer needs to save the return value of pc_memory_init() and xen_load_linux(), which makes it more similar to pc_q35_init(). The return type & value of pc_memory_init() and xen_load_linux() are not changed themselves; maybe we'll need their return values sometime later.
