arch/arm64/boot/dts/freescale/fsl-ls1046a-frwy.dts is using only jedec,spi-nor

Renesas and our SOM are using it.
arch/arm64/boot/dts/renesas/rzg2l-smarc-som.dtsi:310:           compatible = 
"micron,mt25qu512a", "jedec,spi-nor";
arch/arm64/boot/dts/renesas/rzg2lc-smarc-som.dtsi:239:          compatible = 
"micron,mt25qu512a", "jedec,spi-nor";
arch/arm64/boot/dts/xilinx/zynqmp-sm-k26-revA.dts:136:          compatible = 
"micron,mt25qu512a", "jedec,spi-nor"; /* 64MB */

Rob/Krzysztof/Conor: What's the recommendation? I see 02g variant listed and 
micron-st also has 256a/512a variants.

Thanks,
Michal
