jtag: basic support for P&E Micro OSBDM (aka OSJTAG) adapter 

This driver provides support for the P&E Micro OSBDM adapter (sometimes
named as OSJTAG), mounted on the Freescale TWRK60N512 bord. Thus, it
provides a quick start when working with this board. The driver doesn't
use BDM commands, but work with OSBDM adapter using only JTAG commands.
