BSP for TMS570LS31x Hercules Development Kit from TI (TMS570LS3137)

Included variants:
  tms570ls3137_hdk_intram - place code and data into internal SRAM
  tms570ls3137_hdk_sdram - place code into external SDRAM and data to SRAM
  tms570ls3137_hdk - variant prepared for stand-alone RTEMS aplication
                      stored and running directly from flash. Not working yet.

Chip initialization code not included in BSP.
External startup generated by TI's HalCoGen was used	for
testing and debugging.

Patch version 2
  - most of the formatting suggestion applied.
  - BSP converted to use clock shell
  - console driver "set attributes" tested. Baudrate change working
Patch version 3
  - more formatting changes.
  - removed leftover defines and test functions
Todo:
  refactor header files (name register fields)
