[U-Boot] [PATCH] Licenses: Re-add introduction to README, add Exceptions file

[Tom Rini <trini@ti.com>]

From: Wolfgang Denk <wd@denx.de>

The Licenses/Exceptions file describes the standalone license exception.
Add back our long-standing introductory remarks to Licenses/README and
fix a few spelling problems

[trini: Grab differences between v1 and v3, apply separately, to avoid a
new branch on Wolfgang's side]

 Like many other projects, U-Boot has a tradition of including big
 blocks of License headers in all files.  This not only blows up the
 source code with mostly redundant information, but also makes it very
 difficult to generate License Clearing Reports.  An additional problem
-is that even the same linces are referred to by a number of slightly
-varying text blocks (full, abbreviated, with obsolted / older address
+is that even the same licenses are referred to by a number of
+slightly varying text blocks (full, abbreviated, different
+indentation, line wrapping and/or white space, with obsolete address
 information, ...) which makes automatic processing a nightmare.
 
 To make this easier, such license headers in the source files will be
-replaced with a single line reference to Unique Lincense Identifiers
