[SWDEV-451104] Update static --board + amdsmi_get_gpu_board_info()

Updates:
    * Expanded `amdsmi_get_gpu_board_info()` amdsmi_board_info_t structure size
      Updated sizes that work for retrieving relevant board
      information across AMD's ASIC products.
    * Fixed `amdsmi_get_gpu_board_info()` to no longer return junk char strings
