Patch from "John M. Mills" <jmills@tga.com> with subsequent cleanup from

Ralf Corsepius <corsepiu@faw.uni-ulm.de> that adds initial Hitachi SH-2
support to RTEMS.  Ralf's comments are:

    Changes:
    ------
    1. SH-Port:
    * Many files renamed.
    * CONSOLE_DEVNAME  and MHZ defines removed from libcpu.
    * console.c moved to libbsp/sh/shared, build in libbsp/sh/<BSP>/console
      applying VPATH.
    * CONSOLE_DEVNAME made BSP-specific, replacement is defined in bsp.h
    * MHZ define replaced with HZ (extendent resolution) in custom/*.cfg
    * -DHZ=HZ  used in bspstart.c, only
    * Makefile variable HZ used in bsp-dependent directories only.

    2. SH1-Port
    * clock-driver rewritten to provide better resolution for odd CPU
      frequencies. This driver is only partially tested on hardware, ie.
      sightly experimental, but I don't expect severe problems with it.
    * Polling SCI-driver added. This driver is experimental and completly
      untested yet. Therefore it is not yet used for the console (/dev/console
      is still pointing to /dev/null, cf. gensh1/bsp.h).
    * minor changes to the timer driver
    * SH1 specific delay()/CPU_delay() now is implemented as a function

    3. SH2-Port
    * Merged
    * IMO, the code is still in its infancy. Therefore I have interspersed
      comments (FIXME) it for items which I think John should look after.
    * sci and console drivers partially rewritten and extended (John, I hope
      you don't mind).
    * Copyright notices are not yet adapted
