Add fields for the three bootm parameters and other things needed for
booting. Also add a helper to set up the struct correctly.

  * struct bootm_info() - information used when processing images to boot
  *
+ * These mirror the first three arguments of the bootm command. They are
+ * designed to handle any type of image, but typically it is a FIT.
+ *
+ * @addr_img: Address of image to bootm, as passed to
+ *	genimg_get_kernel_addr_fit() for processing:
+ *
+ *    NULL: Usees default load address, i.e. image_load_addr
+ *    <addr>: Uses hex address
+ *
+ * For FIT:
+ *    "[<addr>]#<conf>": Uses address (or image_load_addr) and also specifies
+ *	the FIT configuration to use
+ *    "[<addr>]:<subimage>": Uses address (or image_load_addr) and also
+ *	specifies the subimage name containing the OS
+ *
+ * @conf_ramdisk: Address (or with FIT, the name) of the ramdisk image, as
+ *	passed to boot_get_ramdisk() for processing, or NULL for none
+ * @conf_fdt: Address (or with FIT, the name) of the FDT image, as passed to
+ *	boot_get_fdt() for processing, or NULL for none
+ * @boot_progress: true to show boot progress
  * @images: images information
+ * @cmd_name: command which invoked this operation, e.g. "bootm"
  * @argc: Number of arguments to the command (excluding the actual command).
  *	This is 0 if there are no arguments
  * @argv: NULL-terminated list of arguments, or NULL if there are no arguments
