dt-bindings: memory: Add jedec,lpddrX-channel binding
This patch adds a new device tree binding for an LPDDR channel to serve
as a top-level organizing node for LPDDR part nodes nested below it. An
LPDDR channel needs to have an "io-width" property to describe its width
(this is important because this width does not always match the io-width
of the part number, indicating that multiple parts are wired in parallel
on the same channel), as well as one or more nested "rank@X" nodes.
Those represent information about the individual ranks of each LPDDR
part connected on that channel and should match the existing
"jedec,lpddrX" bindings for individual LPDDR parts.
New platforms should be using this node -- the existing practice of
providing a raw, toplevel "jedec,lpddrX" node without indication of how
many identical parts are in the system should be considered deprecated.

dt-bindings: memory: Add jedec,lpddr4 and jedec,lpddr5 bindings
This patch adds bindings for LPDDR4 and LPDDR5 memory analogous to the
existing bindings for LPDDR2 and LPDDR3. For now, the new types are only
needed for topology description, so other properties like timing
parameters are omitted. They can be added later if needed.

dt-bindings: memory: Add numeric LPDDR compatible string variant
This patch allows a new kind of compatible string for LPDDR parts in the
device tree bindings, in addition to the existing hardcoded
<vendor>,<part-number> strings. The new format contains manufacturer and
part (revision) information in numerical form, such as lpddr3-ff,0201
for an LPDDR3 part with manufacturer ID ff and revision ID 0201. This
helps cases where LPDDR parts are probed at runtime by boot firmware and
cannot be matched to hardcoded part numbers, such as the firmware on the
qcom/sc7280-herobrine boards does (which supports 4 different memory
configurations at the moment, and more are expected to be added later at
a point where the boot firmware can no longer be updated to specifically
accommodate them).
