Remove the reference to the global variable, rtc_state, by passing function argument to cmos_init_hd(), cmos_init(). And following d9c3231019a0fbacbe15dcb26a0e3708b726af77 which uses qemu_irq for powerdown to eliminate nasty #ifdef (TARGET_xxx), this patch removes #ifdef(TARGET_I386) and global variable rtc_state.
