xilinx: common: Change board_info[] handling

Browse Source 
Origin code was allocating only pointers to struct xilinx_board_description
and there was separate allocation for structure self and freeing in case of
failure.
The code is directly allocating space for all structures by one calloc to
simlify logic.
