The memory subsystem on Tegra194 encompasses both the memory and
external memory controllers. The EMC is represented as a subnode of the
MC and a ranges property is used to describe the register ranges.
A dma-ranges property is also added to describe that all memory clients
can address up to 39 bits using the memory controller client interface
(MCCIF), unless otherwise limited by the DMA engines of the hardware. A
memory client can technically use 40 bits of addresses, but the memory
controller on Tegra194 uses bit 39 to determine the XBAR format used to
access memory. Use of this bit needs to be explicitly controlled by the
operating system drivers for devices that can use this on-the-fly format
conversion. Using the dma-ranges property prevents the operating system
from using the bit implicitly, for example in I/O virtual address
mappings.

Add the external memory controller as a child device of the memory
controller on Tegra186. The memory controller really represents the
memory subsystem that encompasses both the memory and external memory
controllers. The external memory controller uses the BPMP to obtain the
list of supported EMC frequencies and set the EMC frequency.
Also set up the dma-ranges property to describe that all memory clients
can address up to 40 bits using the memory controller client interface
(MCCIF), unless otherwise limited by the DMA engines of the hardware.

The NVIDIA Tegra186 SoC contains a memory subsystem composed of the
memory controller and the external memory controller. The memory
controller provides interfaces for the memory clients to access the
memory. Accesses can be either bounced through the SMMU for IOVA
translation or directly to the EMC.
The bulk of the programming of the external memory controller happens
through interfaces exposed by the BPMP. Describe this relationship by
adding a phandle reference to the BPMP to the EMC node.

Convert the device tree bindings for the Tegra124 EMC controller to the
DT schema format using json-schema. While at it, clean up the binding a
little bit by removing any mention of how RAM code and clock frequency
are represented in unit-addresses (which they aren't) and by adding the
EMC clock without which the EMC controller can't change the frequency at
which the external memory is clocked. While this is technically an ABI
break (the clock was not required before), this should be fine because
there isn't much that the EMC driver can do without access to the EMC
clock.
