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.
