Subject: dt-bindings: mtd: brcm,trx: Add brcm,trx-magic
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.

Subject: mtd: parsers: trx: Allow to specify trx-magic in DT
Buffalo uses a different TRX magic for every device, to be able to use
this trx parser, make it possible to specify the TRX magic in device
tree. If no TRX magic is specified in device tree, the standard value
will be used. This value should only be specified if a vendor chooses to
use a non standard TRX magic.
