arm64: dts: freescale: sl28: add variant 1 



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.

 * Device Tree file for the Kontron SMARC-sAL28 board.

 *

 * This is for the network variant 1 which has one ethernet port. It is

 * different than the base variant, which also has one port, but here the

 * port is connected via RGMII. This port is not TSN aware.

 * None of the  four SerDes lanes are used by the module, instead they are

 * all led out to the carrier for customer use.
