BCM4908 devices with U-Boot use pkgtb firmware format. It's based on
U-Boot's FIT: DTB with configurations, images & embedded data.
This format contains bootfs, rootfs and optionally a first stage U-Boot
loader. Contained images need to be extracted & flashed.
Broadcom used two sets of firmwares: main & backup. It uses UBI volumes
"metadata1" & "metadata2" for storing U-Boot env variables with info
about flashed images.

This results in setting format specific data (format info, extract
commands) in a single function. It should help maintaining sysupgrade
code.
This change has been tested on Asus GT-AC5300 and Netgear R8000P.

It supports flashing OpenWrt images (bootfs & UBI upgrade) as well as
vendor images (whole MTD partition write).
Upgrading cferom is unsupported. It requires copying device specific
data (like MAC) to target image before flashing.

So far, board.d files were having execute bit set and contained a
shebang. However, they are just sourced in board_detect, with an
apparantly unnecessary check for execute permission beforehand.
Replace this check by one for existance and make the board.d files
"normal" files, as would be expected in /etc anyway.
Note:
This removes an apparantly unused '#!/bin/sh /etc/rc.common' in
target/linux/bcm47xx/base-files/etc/board.d/01_network
