preloader_console_init is used for printing SPL boot banner that usually called from spl_board_init. The current spl_board_init in evb and rock960 is enabling explicit pinctrl, debug uart prior to calling preloader_console_init which eventually not required since board_init_f is already enabled debug uart. So, drop those explicit enablement calls from spl_board_init of evb, rock960. Tested this by enabling CONFIG_SPL_BOARD_INIT and adding u-boot,dm-pre-reloc property for uart node.
