Now that chips and devices are treated differently in sconfig, this change gets rid of struct header and add_header function which were responsible for maintaining list of headers that need to be added to static.c. Instead, struct chip is re-factored into struct chip and struct chip_instance, where chip is a list of unique chips required by the mainboard whereas chip_instance is an instance of the chip. One chip can have multiple instances dependending upon the devices in the system. Also, struct device is updated to hold a pointer to chip instance instead of the chip structure. This unique list of chips is then used to add appropriate headers to static.c BUG=b:80081934 TEST=Verified using abuild that all boards compile successfully.
