Subject: [PATCH] arm64: dts: rockchip: add spiX aliases for rk3399

It's nicer to see this:

    # ls -l /sys/bus/spi/devices/
    total 0
    lrwxrwxrwx 1 root root 0 Dec 31  1969 spi0.0 -> ../../../devices/platform/ff1c0000.spi/spi_master/spi0/spi0.0
    lrwxrwxrwx 1 root root 0 Dec 31  1969 spi1.0 -> ../../../devices/platform/ff1d0000.spi/spi_master/spi1/spi1.0
    lrwxrwxrwx 1 root root 0 Dec 31  1969 spi2.0 -> ../../../devices/platform/ff1e0000.spi/spi_master/spi2/spi2.0
    lrwxrwxrwx 1 root root 0 Dec 31  1969 spi5.0 -> ../../../devices/platform/ff200000.spi/spi_master/spi5/spi5.0

than this:

    # ls -l /sys/bus/spi/devices/
    total 0
    lrwxrwxrwx 1 root root 0 Dec 31  1969 spi32763.0 -> ../../../devices/platform/ff200000.spi/spi_master/spi32763/spi32763.0
    lrwxrwxrwx 1 root root 0 Dec 31  1969 spi32764.0 -> ../../../devices/platform/ff1e0000.spi/spi_master/spi32764/spi32764.0
    lrwxrwxrwx 1 root root 0 Dec 31  1969 spi32765.0 -> ../../../devices/platform/ff1d0000.spi/spi_master/spi32765/spi32765.0
    lrwxrwxrwx 1 root root 0 Dec 31  1969 spi32766.0 -> ../../../devices/platform/ff1c0000.spi/spi_master/spi32766/spi32766.0

With the latter, it's much clearer which bus devices are on.
