Subject: [PATCH v12 3/7] arm64: dts: allwinner: Add Allwinner H616 .dtsi file

This (relatively) new SoC is similar to the H6, but drops the (broken)
PCIe support and the USB 3.0 controller. It also gets the management
controller removed, which in turn removes *some*, but not all of the
devices formerly dedicated to the ARISC (CPUS).
And while there is still the extra sunxi interrupt controller, the
package lacks the corresponding NMI pin, so no interrupts for the PMIC.

The reserved memory node is actually handled by Trusted Firmware now,
but U-Boot fails to propagate this to a separately loaded DTB, so we
keep it in here for now, until U-Boot learns to do this properly.

Other than the decision about the reserved-memory node, which is being discussed
in the v11 thread, this looks good to me. Just a few minor comments below.

Please use the recently-added symbolic constants for the RTC clocks.

Future note: this will be affected by [1] which adds a fallback compatible for
variants with offload support. That way we don't have to support them all
individually in the driver if/when we implement that.

Nit: clocks then resets then syscon, to follow the usual order.

Since the RTC clock indices were formalized in the binding, this is no longer
