kbuild: move asm-offsets.h rule to ./Kbuild ...

Currently, MIPS is the only architecture that needs
include/generated/asm-offsets.h, but we have got ./Kbuild file now.

It is a good reason to move asm-offsets.h rule from arch/mips/Makefile
to ./Kbuild and add dummy asm-offsets.c for the other architectures.
asm-offsets.h would be useful for all the architectures.

This commit does not implement include/generated/bounds.h,
but if necessary, it is easy to implement it.

treewide: remove address of the Free Software Foundation ...

The FSF address has changed; The FSF site says that
address is

  Free Software Foundation

(see http://www.fsf.org/about/contact/)

Instead of updating it each time the address changes,
just drop it completely treewide.

commands: harmonize in-barebox documentation ...

This patch does probably too much, but it's hard (and very
cumbersome/time consuming) to break it out. What is does is this:

* each command has one short description, e.g. "list MUX configuration"
* made sure the short descriptions start lowercase
* each command has one usage. That string contains just the
  options, e.g. "[-npn]". It's not part of the long help text.
* that is, it doesn't say "[OPTIONS]" anymore, every usable option
  is listed by character in this (short) option string (the long
  description is in the long help text, as before)
* help texts have been reworked, to make them
  - sometimes smaller
  - sometimes describe the options better
  - more often present themselves in a nicer format
* all long help texts are now created with BUSYBOX_CMD_HELP_
  macros, no more 'static const __maybe_unused char cmd_foobar_help[]'
* made sure the long help texts starts uppercase
* because cmdtp->name and cmdtp->opts together provide the new usage,
  all "Usage: foobar" texts have been removed from the long help texts
* BUSYBOX_CMD_HELP_TEXT() provides the trailing newline by itself, this
  is nicer in the source code
* BUSYBOX_CMD_HELP_OPT() provides the trailing newline by itself
* made sure no line gets longer than 77 characters
* delibertely renamed cmdtp->usage, so that we can get compile-time
  errors (e.g. in out-of-tree modules that use register_command()
* the 'help' command can now always emit the usage, even without
  compiled long help texts
* 'help -v' gives a list of commands with their short description, this
  is similar like the old "help" command before my patchset
* 'help -a' gives out help of all commands

commands: group 'help' output ...

The old output of "help" was just producing a long list, that usually
scrolled of the screen (even on a X11 terminal). This list is more
compact, and also sorted by groups.

The old output format (plus grouping) is now available with 'help -v'.

Example:

   Information commands:
     ?, devinfo, help, iomem, meminfo, version
   Boot commands:
     boot, bootm, go, loadb, loads, loadx, loady, saves, uimage
   ...

Add OpenRISC arch ...

OpenRISC is the original flagship project of the OpenCores community.
This project aims to develop a series of general purpose open source
RISC CPU architectures.

A team from OpenCores provided the first implementation, the OpenRISC
1200, written in the Verilog hardware description language.

Even though I should have created an mach-or1200 directory, it is not
necessary for now. The OpenRISC 1200 CPU is the only one available and
it will be for some time.
