Devicetree changes for omaps for v5.14 merge window

Mostly just clean-up for device tree binding checks with
few other clean-up patches:

- Drop ov5640 sensor for dra76-evm, it's just one of the
  optional additional sensors and makes hard to use any of
  the other options, TI is using the devicetree overlay
  snippets for these

- Group the phandles in osd3358-sm-red to make the files
  more readable

- A series of gpio clean-up patches to follow the binding
  documentation

- Move ti,no-reset related properties to the target module
  level, the ti-sysc driver handles them also in the child
  but they really belong to the target module

- Drop the unnecessary uart compatible entries to make the
  binding check to work

- Mailbox related updates to make the binding check to
  work
