fpga: zynq: Remove post config info message for SPL

The drivers informs the user that a post config was not run after FPGA
configuration. This message is unnecessary in SPL because the
ps7_post_config function is called via spl_board_prepare_for_boot
function before jump_to_image_no_args function from board_init_r
function.
