rockchip: add boot-mode support for rk3288, rk3036 rockchip platform have a protocol to pass the the kernel reboot mode to bootloader by some special registers when system reboot. In bootloader we should read it and take action. We can only setup boot_mode in board_late_init becasue "setenv" need env setuped. So add CONFIG_BOARD_LATE_INIT to common header and use a entry "rk_board_late_init" to replace "board_late_init" in board file.

rockchip: add support for enter to bootrom download mode Rockchip bootrom will enter download mode if it returns from spl/tpl with a non-zero value and couldn't find a valid image in the backup partition. This patch provide a method to instruct the system to back to bootrom download mode by checking the BROM_DOWNLOAD_FLAG register. As the bootrom download function relys on some modules such as interrupts, so we need to back to bootrom as early as possbile before the tpl/spl code override the interrupt configurations.
