Increase sound-dai-cells to 1 to allow using the DAIs in the codec
corresponding to AIF2 and AIF3.
The generic ASoC OF code supports a #sound-dai-cells value of 0 or 1
with no impact to the driver, so this is a backward-compatible change.

Increase #sound-dai-cells on the digital codec to allow using the other
DAIs provided by the codec for AIF2 and AIF3.

Now that the sun8i-codec driver supports AIF2 and AIF3, boards can use
them in DAI links. Add the necessary pinmux nodes.

If the device suspend process begins before the mmc host's autosuspend
timeout, the host will continue running during system sleep. Avoid
this by forcing runtime suspend during a global suspend transition.

Only one register, SUNXI_IR_CIR_REG, is accessed from outside the
interrupt handler, and that register is not accessed from inside it.
As there is no overlap between different contexts, no lock is needed.

The register writes during driver removal occur after the device is
already put back in reset, so they never had any effect.

- Only add wakeup capability if "wakeup-source" is present
- Warn but do not error out if setting the wake IRQ fails
- Add "wakeup-source" property to PinePhone device tree

PinePhone volume keys are connected to the LRADC in the A64. Users may
want to use them to wake the device from sleep. Support this by
declaring the LRADC as a wakeup source.

The LRADC provides an interrupt that can be used to wake the system.
Signify this by accepting a "wakeup-source" property in the binding.

The binding of R_INTC was updated to allow specifying interrupts other
than the external NMI, since routing those interrupts through the R_INTC
driver allows using them for wakeup.
Update the device trees to use the new binding.

- Use an enum for the device tree binding.
