[PATCH 1/1] ARM: dts: imx6ul: add spdif node

[Jörg Krause]

The i.MX6UL has a SPDIF located at start address 0x02004000 in the
AIPS-1 memory region [1].

SPDIF is also available on i.MX6ULL [2], so imx6ull.dtsi is fine.

    03/2017, Table-2-2 AIPS-1 memory map, p. 158
[2] i.MX 6ULL Applications Processor Reference Manual, Rev. 1,
    11/2017, Table-2-2 AIPS-1 memory map, p. 178
