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.

USB is a bit tricky: host controller 0, 1 and 3 depend on some help from
controller and PHY 2, so we need to include one reset line and one
clock gate from HCI 2 into every other HCI node, plus need some nasty
quirk.

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.

As far as I can see, the IOMMU hasn't changed between the H6 and the
H616, so it would be worth enabling
