Remove the regulators node entirely because its children do not have any
unit addresses. This fixes DTC warning:
Warning (simple_bus_reg): /regulators/regulator-0: missing or empty reg/ranges property
Signed-off-by: Krzysztof Kozlowski <[email protected]>

Changes since v1:
1. Remove the node, not only compatible, as pointed out by Sylwester.

What about removing the regulators node from other boards:
exynos4412-origen.dts, exynos5420-smdk5420.dts and exynos5250-arndale.dts?
On the other hand, maybe it would be really easier to add missing
address/size-cells properties to exynos4210-trats.dts/regulators node?
Best regards

Indeed let's keep it consistent so in such case better to add here
proper address/size-cells.
Thanks for feedback!
Best regards,

Actually more of DTSes put fixed regulators directly in root node, not
under "regulators" node:
exynos3250-monk.dts
exynos4210-i9100.dts
exynos4210-origen.dts
exynos4210-universal_c210.dts
exynos4412-galaxy-s3.dtsi
exynos4412-midas.dtsi
exynos4412-n710x.dts
exynos4412-odroidx.dts
exynos5250-smdk5250.dts
exynos5250-snow-common.dtsi
exynos5420-peach-pit.dts
exynos5800-peach-pi.dts
If we want it to be consistent, it's easier to remove the regulator
nodes from exynos4412-origen.dts, exynos5420-smdk5420.dts and
exynos5250-arndale.dts.
Best regards,
Krzysztof

Feel free, I'm fine with both approaches.
