[v3,4/4] hw/i386/pc: Inline pc_cmos_init() into pc_cmos_init_late() and remove it

Commit Message

Now that pc_cmos_init() doesn't populate the X86MachineState::rtc attribute any
longer, its duties can be merged into pc_cmos_init_late() which is called within
machine_done notifier. This frees pc_piix and pc_q35 from explicit CMOS
initialization.
