[PATCH v2 net-next 04/10] dt-bindings: memory: mt7621: add syscon as compatible string

[Arınç ÜNAL <arinc.unal@xxxxxxxxxx>]

Add syscon as a constant string on the compatible property as it's required
for the SoC to work. Update the example accordingly.

Fixes: 5278e4a181ff ("dt-bindings: memory: add binding for Mediatek's MT7621 SDRAM memory controller")
