[PATCH 01/17] android: boot: rename andr_img_hdr -> andr_boot_img_hdr_v0_v1_v2

[Safae Ouajih <souajih@baylibre.com>]

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)

To maintain support for version v0, v1 and v2 while introducing
version 3 and 4, this struct name must change to refer to the header
structure before v3.
