[U-Boot] [PATCH v2 1/1] colibri_imx7: introduce androidboot wrapper

[Igor Opaniuk]

From: Igor Opaniuk <igor.opaniuk at toradex.com>

1. Introduce androidboot wrapper for booting AOSP.
2. Add partitions_android env var for simplifying the process of
writing new gpt table from U-boot shell/fastboot.

Signed-off-by: Igor Opaniuk <igor.opaniuk at toradex.com>
---

v2:
- add proper serialnum value for bootargs instead hardcoded stub
- add invocation of m4 aux binary
