This adds the description of an additional property which allows to
specify a custom partition parser magic to detect a trx partition.
Buffalo has multiple device which are using the trx format, but with
different magic values.

BCM4908 uses fixed partitions layout but function of some partitions may
vary. Some devices use multiple firmware partitions and those partitions
should be marked to let system discover their purpose.

Single partition binding is quite common and may be:
1. Used by multiple parsers
2. Extended for more specific cases
Move it to separated file to avoid code duplication.

This standardizes its documentation, allows validating with Makefile
checks and helps writing DTS files.
Noticeable changes:
1. Dropped "Partitions can be represented by sub-nodes of a flash
device." as we also support subpartitions (don't have to be part of
flash device node)
2. Dropped "to Linux" as bindings are meant to be os agnostic.

Broadcom based home router devices use TRX firmware format. It's a
container that can hold few partitions. If operating system is expected
to access them it has to understand that format and parse flash data
accordingly.

Broadcom based home router devices use partitions which have to be
discovered in a specific way. They are not fixed and there is not any
standard partition table. This commit adds and describes a new custom
