This series replace a number of device specific variants of the
"denx,uimage" partition splitter with a unified parser, using optional
device-tree properties to describe deviations from the standard U-Boot
Image.

This is now tested on a number of devices.  Although tests only cover
a fraction of the affected hardware, I believe it's a good sign that
all tests have been successful.  At least I didn't screw up completely
:-)

There is still no test coverage of devices previously using the
"fonfxc", "sge", "allnet,uimage" or "edimax,uimage" compatibles.

Changes in v4:
 - changed license of dt-bindings docs
 - added IH_MAGIC_OKLI, FW_EDIMAX_OFFSET and FW_MAGIC_EDIMAX macros and
   used these instead of the magic values in the DTS files
 - removed unwanted space after comma in patch subjects

Changes in v3:
 - rebased onto current master
 - included a number of new and/or forgotton devices:
    ar7242_engenius_eap350-v1
    ar7242_engenius_ecb350-v1
    ar9341_engenius_eap300-v2
    ar9344_engenius_eap600
    ar9344_engenius_ecb600
    qca9557_engenius_enstationac-v1
    qca9558_belkin_f9j1108-v2
    qca9558_belkin_f9k1115-v2
    mt7620a_edimax_ew-7476rpc
    mt7620a_edimax_ew-7478ac
 - added Tested-by tags for some of the okli and netgear devices

Changes in v2
 - added documentation of the properties, almost upstreamable
 - added a device tree header shared with the driver
 - changed property names to openwrt,foo and tied these to an
   openwrt,uimage compatible string
 - split out the definition of the properties from the deletion of the
   "edimax,uimage" parser
