Add another board ... OMAP2420 "H4" board.  This won't be very widely
used with OpenOCD, but with mainline support in both U-Boot and Linux
it at least makes for a more complete set (and another testcase).

This is incomplete support in several respects.  The ARM11 support is
not very deep yet; most registers aren't available, and the ETM can't
be hooked up.  Plus, there's no script for OMAP-specific stuff like
setting up the SDRAM controller.  Eventually the same NAND controller
driver should work with OMAP2 and OMAP3.
