Sam Protsenko 4d579a4394 libavb: Update libavb to current AOSP master
Update libavb to commit 5fbb42a189aa in AOSP/master, because new version
has support for super partition [1], which we need for implementing
Android dynamic partitions. All changes from previous patches for libavb
in U-Boot are accounted for in this commit:
  - commit ecc6f6bea6 ("libavb: Handle wrong hashtree_error_mode in
                          avb_append_options()")
  - commit 897a1d947e ("libavb: Update SPDX tag style")
  - commit d8f9d2af96 ("avb2.0: add Android Verified Boot 2.0 library")

Tested on X15:

    ## Android Verified Boot 2.0 version 1.1.0
    read_is_device_unlocked not supported yet
    read_rollback_index not supported yet
    read_is_device_unlocked not supported yet
    Verification passed successfully
    AVB verification OK.

Unit test passes:

    $ ./test/py/test.py --bd sandbox --build -k test_avb

      test/py/tests/test_android/test_avb.py ss..s.
