Add a new start address field to struct bootcmdline to easily match a cmdline to the corresponding bootmodule. This is useful for debugging (not actually needed for functionalities today, but could be.) Instead of printing the index in the cmdline array, print the start address of the corresponding bootmodule for each cmdline in early_print_info.
