zynq: Add support to find bootmode
Added support to find the bootmodes by reading slcr bootmode register. this can be helpful to autoboot the configurations w.r.t a specified bootmode. Added this functionality on board_late_init as it's not needed for normal initializtion part. Signed-off-by: Jagannadha Sutradharudu Teki <jaganna@xilinx.com>
