[PATCH] ARM: dts: stm32: add resets property to m_can nodes in the stm32mp153

[Marc Kleine-Budde]

On the STM32MP153 the m_cam IP cores (a.k.a. FDCAN) have an external
shared reset in the RCC. Add the reset to both m_can nodes.

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade


This patch series was applied (using b4) to base:
 Base: using specified base-commit 1a32f7427eb3d1248bc64cd745b93f88cc838933

If this is not the correct base, please add 'base-commit' tag
(or use b4 which does this automatically)
