[U-Boot] [PATCH v2 07/11] samsung: misc: set_board_info: check the board type to set fdt file name

[Przemyslaw Marczak]

This change adds a call to the get_board_type_fdt() function before setting
the "fdtfile" environment variable.

For CONFIG_BOARD_TYPES below function is called:
- const char *get_board_type_fdt(void) - should return a pointer
  to the board type string.

This is useful in case of run many boards with just one config.
