boardctl(): Add a new non-standard OS interface. This is similar to a driver IOCTL call. But this is an IOCTL call directly on the board logic. This function will eventually replace all of the ad hoc OS interfaces that are current used to perform application specific intialiation and application driver test confifuration. It essentially formalizes and institutionalizes these rogue interface in to at least a single crazy call.

+ * Name: boardctl
+ *
+ * Description:
+ *   In a small embedded system, there will typically be a much greater
+ *   interaction between application and low-level board features.  The
+ *   canonically correct to implement such interactions is by implementing a
+ *   character driver and performing the interactions via low level ioctl
+ *   calls.  This, however, may not be practical in many cases and will lead
+ *   to "correct" but awkward implementations.
+ *
+ *   boardctl() is non-standard OS interface to alleviate the problem.  It
+ *   basically circumvents the normal device driver ioctl interlace and allows
+ *   the application to perform direction IOCTL-like calls to the board-specific
+ *   logic.  In it is especially useful for setting up board operational and
+ *   test configurations.
+ *
+ * Input Parameters:
+ *   cmd - Identifies the board command to be executed
+ *   arg - The argument that accompanies the command.  The nature of the
+ *         argument is determined by the specific command.
+ *
+ * Returned Value:
+ *   On success zero (OK) is returned; -1 (ERROR) is returned on failure
+ *   with the errno variable to to indicate the nature of the failure.
+ *
