[PATCH v2] udoo_neo: fix udoo neo UNDEFINED

get_board_value function fails to get the right board configuration on
second time that is call. This patch move get_board_value function at
spl level, once is call, store the right configuration into gd static
variable gd->board_type and fix the previous error.
get_board_value is now call only one time.

Changes since v1
 - get_board_value declared as void
 - fix gd->board_type, re-initialized after spl
