As it currently is, python files are formatted using the general rules
in .editorconfig - this means that 8-character hard tabs are used, which
is not the recommended behaviour according to the PEP-8 standard.  This
patch correct this, and additionally limits the line length to 79
characters as required by the standard.

The project has been renamed from "Arm Trusted Firmware (ATF)" to
"Trusted Firmware-A (TF-A)" long ago. A few references to the old
project name that still remained in various places have now been
removed.

This change doesn't affect any platform files. Any "ATF" references
inside platform files, still remain.

The .editorconfig file provides an editor agnostic definition of a
project's file format requirements.

This change should have little impact on users, but, it is hoped, will
help those who move across projects avoid making mistakes because of
foreign project editor configuration settings.
