[PATCH v3 02/17] dt-bindings: mtd: Remove useless file about partitions

There is already a real partitions.yaml file, so assuming everybody
knows hot to read yaml schema now, this text file is no longer needed,
so drop it.

Depending on the situation, the lines referring to this file are either
dropped or edited to point to mtd.yaml which includes partition{,s}.yaml.

-Flash partitions in device tree
-Flash devices can be partitioned into one or more functional ranges (e.g. "boot
-code", "nvram", "kernel").
-Different devices may be partitioned in a different ways. Some may use a fixed
-flash layout set at production time. Some may use on-flash table that describes
-the geometry and naming/purpose of each functional region. It is also possible
-to see these methods mixed.
-To assist system software in locating partitions, we allow describing which
-method is used for a given flash device. To describe the method there should be
-a subnode of the flash device that is named 'partitions'. It must have a
-'compatible' property, which is used to identify the method to use.
-When a single partition is represented with a DT node (it depends on a used
-format) it may also be described using above rules ('compatible' and optionally
-some extra properties / subnodes). It allows describing more complex,
-hierarchical (multi-level) layouts and should be used if there is some
-significant relation between partitions or some partition internally uses
-another partitioning method.
-Available bindings are listed in the "partitions" subdirectory.
-Deprecated: partitions defined in flash node
-For backwards compatibility partitions as direct subnodes of the flash device are
-supported. This use is discouraged.
-NOTE: also for backwards compatibility, direct subnodes that have a compatible
-string are not considered partitions, as they may be used for other bindings.
