Revert "ARM: dts: stm32: add CAN support on stm32f746"

This reverts commit 0920ccd.

The commit 0920ccd ("ARM: dts: stm32: add CAN support on
stm32f746") depends on the patch "dt-bindings: mfd: stm32f7: add
binding definition for CAN3" [1], which is not in net/main, yet. This
results in a parsing error of "stm32f746.dtsi".

So revert this commit.
