dt-bindings: Add missing 'additionalProperties: false'

Setting 'additionalProperties: false' is frequently omitted, but is
important in order to check that there aren't extra undocumented
properties in a binding.

Ideally, we'd just add this automatically and make this the default, but
there's some cases where it doesn't work. For example, if a common
schema is referenced, then properties in the common schema aren't part
of what's considered for 'additionalProperties'. Also, sometimes there
are bus specific properties such as 'spi-max-frequency' that go into
bus child nodes, but aren't defined in the child node's schema.

So let's stick with the json-schema defined default and add
'additionalProperties: false' where needed. This will be a continual
review comment and game of wack-a-mole.

dt-bindings: media: csi: Fix clocks description

Commit 1de243b07666 ("media: dt-bindings: media: sun4i-csi: Add compatible
for CSI1 on A10/A20") introduced support for the CSI1 controller on A10 and
A20 that unlike CSI0 doesn't have an ISP and therefore only have two
clocks, the bus and module clocks.

The clocks and clock-names properties have thus been modified to allow
either two or tree clocks. However, the current list has the ISP clock at
the second position, which means the bindings expects a list of either
bus and isp, or bus, isp and mod. The initial intent of the patch was
obviously to have bus and mod in the former case.

Let's fix the binding so that it validates properly.

dt-bindings: net: mdio: remove compatible string from example

Remove vendor specific compatible string from example, otherwise DT YAML
schemas validation may trigger warnings specific to TI ti,davinci_mdio
and not to the generic MDIO example.

For example, the "bus_freq" is required for davinci_mdio, but not required for
generic mdio example. As result following warning will be produced:
 mdio.example.dt.yaml: mdio@5c030000: 'bus_freq' is a required property

MAINTAINERS: remove myself from DT bindings entry

For quite a while Rob has been handling DT binding maintenance, and I
haven't had the time to review bindings outside of a few targetted
cases. Given that, I think being listed in MAINTAINERS is more
misleading than helpful.

of/address: Support multiple 'dma-ranges' entries

Currently, the DMA offset and mask for a device are set based only on the
first 'dma-ranges' entry. We should really be using all the entries. The
kernel doesn't yet support multiple offsets and sizes, so the best we can
do is to find the biggest size for a single offset. The algorithm is
copied from acpi_dma_get_range().

If there's different offsets from the first entry, then we warn and
continue. It really should be an error, but this will likely break
existing DTs.

of/address: use range parser for of_dma_get_range

of_dma_get_range() does the same ranges parsing as
of_pci_range_parser_one(), so let's refactor of_dma_get_range() to use
it instead.

This commit is no functional change. Subsequent commits will parse more
than the 1st dma-ranges entry.
