rockchip: rockpro64: Build u-boot-rockchip-spi.bin

Enable CONFIG_ROCKCHIP_SPI_IMAGE to build u-boot-rockchip-spi.bin.
Define CONFIG_SYS_SPI_U_BOOT_OFFS to write u-boot.itb at the expected
offset. Enable CONFIG_LTO to reduce size of SPL so that the mkimage
output fit before the 0x60000 offset in u-boot-rockchip-spi.bin.
