[PATCH v2 2/2] arm64: dts: freescale: sl28: add variant 1

[Michael Walle]

There is a new variant 1 of this board available. It features up to four
SerDes lanes for customer use. Add a new device tree which features just
the basic peripherals. A customer will then have to modify or append to
this device tree.
