/* Summary
   This function finds the device object given the HAL tag

   Description
   The user associats a device TAG with each West Bridge device
   created.  This tag is passed from the  API functions to and HAL
   functions that need to ID a specific West Bridge device.  This
   tag is also passed in from the user back into the API via
   interrupt functions.  This function allows the API to find the
   device structure associated with a given tag.

   Notes
   This function does a simple linear search for the device based
   on the TAG.  This function is called each time an West Bridge
   interrupt handler is called.  Therefore this works fine for a
   small number of West Bridge devices (e.g. less than five).
   Anything more than this and this methodology will need to be
   updated.

   Returns
   Pointer to a CyAsDevice associated with the tag
