Guillaume La Roque (TI.com) 733f5a6019 boot: android: Add bootconfig support ...

For android vendor boot image version 4 bootconfig is mandatory.[1]

In the android_image_get_ramdisk function, after copying both vendor and
boot ramdisks, we extract all androidboot.* entries from the kernel
command line. These entries are added to the bootconfig section.
We then update the sizes of the ramdisk and bootconfig.
Finally, all androidboot.* entries are removed from the kernel command
line.
