android: boot: ramdisk: support vendor ramdisk
commit c79a2e6823d5a3a2813f66d03023c0a192c27e7e upstream.
Version 3 and 4 of boot image header introduced
vendor boot ramdisk: Please check include/android_image.h
for details.
The ramdisk is now split into a generic ramdisk in boot image
and a vendor ramdisk in vendor boot image.
Support the new vendor ramdisk.
