Strip specific changes from update-from-*master

[Thadeu Lima de Souza Cascardo]

[Impact]
Some code on update-from-*master scripts are specific to the trees and could be on separate files so update-from-*master is the less specific as possible for all the trees. The first step to that are the copying and mangling of files from the master tree.

[Regression potential]
These changes are specific to the process of updating the git tree when preparing new kernels. They should not break the kernel, but might break the process itself.

[Test cases]
The changed scripts have been run and results have been compared with running the original update-from-*master script.
