firmware-utils: bcm4908img: convert into a package

bcm4908img is a tool managing BCM4908 platform images. It's used for
creating them as well as checking, modifying and extracting data from.

It's required by both: host (for building firmware images) and target
(for sysupgrade purposes). Make it a host/target package.

define Package/bcm4908img/description
CFE bootloader for BCM4908 uses custom image format. It consists of:
1. Optional cferom image
2. bootfs JFFS2 partition (cferam, kernel, DTB and optional helper files)
3. padding
4. rootfs simply appended to the bootfs + padding
5. tail with checksum and basic device info
This util allows creating, modifying and extracting from BCM4908 images.
