imx: fix partition reboot fail when debug console is enabled
With partition reboot enabled, console_list variable which is
located in data section is NOT reset, system will be busy looping
in early console operation of flush_loop() if console_list is
NOT 0 while HW console is NOT initialized, so we have to clear
this variable to make partition reboot work.
