[PATCH 2/3] rockchip: Fix SPL link error for Radxa ROCK Pi 4

[FUKAUMI Naoki]

If CONFIG_EFI_CAPSULE_FIRMWARE_RAW, CONFIG_SPL_ENV_SUPPORT, and
CONFIG_SPL_DFU are enabled, linking u-boot-spl will fail.

  LD      spl/u-boot-spl
ld.bfd: drivers/dfu/dfu.o: in function `dfu_init_env_entities':
/home/radxa/u-boot/drivers/dfu/dfu.c:173:(.text.dfu_init_env_entities+0x24): undefined reference to `set_dfu_alt_info'

Compile mach-rockchip/board.c for SPL.
