android: boot: rename andr_img_hdr -> andr_boot_img_hdr_v0

commit d71a732af45e2d3acef92649f4f7986a83175cf4 upstream.

Android introduced boot header version 3 or 4.
The header structure change with version 3 and 4 to support
the new updates such as:
- Introducing Vendor boot image: with a vendor ramdisk
- Bootconfig feature (v4)

Change andr_img_hdr struct name to maintain support for version v0,
v1 and v2 while introducing version 3 and 4.
