Running 'make dtbs_check' with the schema in this patch gives the
following warnings. Consider if they are expected or the schema is
incorrect. These may not be new warnings.

Note that it is not yet a requirement to have 0 warnings for dtbs_check.
This will change in the future.

Full log is available here: https://patchwork.ozlabs.org/patch/1573492


rng@e2010000: compatible:0: 'microchip,sama7g5-trng' is not one of ['atmel,at91sam9g45-trng', 'microchip,sam9x60-trng']
	arch/arm/boot/dts/at91-sama7g5ek.dt.yaml

rng@e2010000: compatible: Additional items are not allowed ('atmel,at91sam9g45-trng' was unexpected)
	arch/arm/boot/dts/at91-sama7g5ek.dt.yaml

rng@e2010000: compatible: ['microchip,sama7g5-trng', 'atmel,at91sam9g45-trng'] is too long

This patch is only converting the existing bindings, so new compatible
is not added. The issue reported here is being fixed in the next patch
(3/8).
