    sunxi: build kernel with sun6i-rtc driver
    
    sun6i-rtc cannot be built as a module and the hardware is only
    present in some of the sunxi SoCs, see driver source:
            { .compatible = "allwinner,sun6i-a31-rtc" },
            { .compatible = "allwinner,sun8i-a23-rtc" },
            { .compatible = "allwinner,sun8i-h3-rtc" },
            { .compatible = "allwinner,sun8i-r40-rtc" },
            { .compatible = "allwinner,sun8i-v3-rtc" },
            { .compatible = "allwinner,sun50i-h5-rtc" },
            { .compatible = "allwinner,sun50i-h6-rtc" },
    
    Set CONFIG_RTC_DRV_SUN6I=y in kernel config file for cortexa7 and
    cortexa53 subtargets which covers all of the above.
