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

According to Documentation/devicetree/bindings/arm/cpus.yaml, the
"enable-method" property should be a property of the individual CPU
nodes, and not of the parent "cpus" container node.
However, on R-Car Gen2 and RZ/G1 SoCs, the property is tied to the
"cpus" node instead.

Secondary CPU bringup and CPU hot (un)plug work regardless, as
arm_dt_init_cpu_maps() falls back to looking in the "cpus" node.

The cpuidle code does not have such a fallback, so it does not detect
the enable-method.  Note that cpuidle does not support the
"renesas,apmu" enable-method yet, so for now this does not make any
difference.

The RZ/G2 boards expect there to be an external clock reference for
USB2 EHCI controllers.  For the Beacon boards, this reference clock
is controlled by a programmable versaclock.  Because the RZ/G2
family has a special clock driver when using an external clock,
the third clock reference in the EHCI node needs to point to this
special clock, called usb2_clksel.

Since the usb2_clksel does not keep the usb_extal clock enabled,
the 4th clock entry for the EHCI nodes needs to reference it to
keep the clock running and make USB functional.

The USB extal clock reference isn't associated to a crystal, it's
associated to a programmable clock, so remove the extal reference,
add the usb2_clksel.  Since usb_extal is referenced by the versaclock,
reference it here so the usb2_clksel can get the proper clock speed
of 50MHz.

The eMMC card has two supplies, VCC and VCCQ. The VCC supplies the NAND
array and the VCCQ supplies the bus. On Condor, the VCC is connected to
3.3V rail, while the VCCQ is connected to 1.8V rail. Adjust the pinmux
to match the bus, which is always operating in 1.8V mode.

While at it, deduplicate the pinmux entries, which are now the same for
both default and UHS modes. We still need the two pinctrl entries to
match the bindings though.
