bsp/tms570: separate Flash variants to one which boots directly and one for boot loader.

The default tms570ls3137_hdk variant is for building RTEMS
application image starting directly from start of Flash.

Variant tms570ls3137_hdk_with_loader skips 256kB at start
of Flash to allow use with application loader.

45Execution
46
47Currently, a bootloader is not used. For test and debug purposes, TI's
48HalCoGen generated application is used to set up the board and then
49the RTEMS application image is loaded using OpenOCD to internal
50EEC SRAM or external DRAM. The following features are
51not implemented in the BSP:
52
53 + Initial complex CPU and peripheral initialization
54 + Cores Self-test
55
56Setup application code is available there:
57          https://github.com/hornmich/tms570ls3137-hdk-sdram
58
59Howto setup TMDS570LS31HDK?
60
61        o Unpack board.
62        o Verify that demo application runs.
63  o Upload bootloader specified above
64  o write BSP application either to sdram or intram and jump to RTEMS start code
