[PATCH v2 02/10] ARM: dts: ls1021a: add TQ-Systems MBLS102xA device tree

[Alexander Stein <alexander.stein@ew.tq-group.com>]

Add device tree for the MBLS102xA mainboard with TQMLS1021A SoM.

Signed-off-by: Alexander Stein <alexander.stein@ew.tq-group.com>
---
Changes in v2:
* Remove unnecessary status = "okay"
* Remove underscore from node names
* Move reg direct below compatiblefor i2c devices
* Remove i2c device nodes without software support
  Add a comment about existance for the device though
