Rather than distributing PC system flash handling across three files, let's
confine it to one. Now, pc_system_firmware_init() creates, configures and cleans
up the system flash which makes the code easier to understand. It also avoids
the extra call to pc_system_flash_cleanup_unused() in the Xen case.

Handling most of smbios data generation in the machine_done notifier is similar
to how the ARM virt machine handles it which also calls smbios_set_defaults()
there. The result is that all pc machines are freed from explicitly worrying
about smbios setup.

In the i386 PC machine, we want to run the pc_cmos_init_late()
function only once the IDE and floppy drive devices have been set up.
We currently do this using qemu_register_reset(), and then have the
function call qemu_unregister_reset() on itself, so it runs exactly
once.
This was an expedient way to do it back in 2010 when we first added
this (in commit c0897e0cb9), but now we have a more obvious point
to do "machine initialization that has to happen after generic device
init": the machine-init-done hook.
Do the pc_cmos_init_late() work from our existing PC machine init
done hook function, so we can drop the use of qemu_register_reset()
and qemu_unregister_reset().
Because the pointers to the devices we need (the IDE buses and the
RTC) are now all in the machine state, we don't need the
pc_cmos_init_late_arg struct and can just pass the PCMachineState
pointer.
