dt-bindings: net: Remove gpmc-eth.txt

There is no GPMC Ethernet compatible or device driver. GPMC is
just a bus interface over which devices like Ethernet controller
can be to.

For SMSC 911x Ethernet chip bindings, please refer to
Documentation/devicetree/bindings/net/smsc,lan9115.yaml

-Device tree bindings for Ethernet chip connected to TI GPMC
-
-Besides being used to interface with external memory devices, the
-General-Purpose Memory Controller can be used to connect Pseudo-SRAM devices
-such as ethernet controllers to processors using the TI GPMC as a data bus.
-
-Ethernet controllers connected to TI GPMC are represented as child nodes of
-the GPMC controller with an "ethernet" name.
-
-All timing relevant properties as well as generic GPMC child properties are
-explained in a separate documents. Please refer to
-Documentation/devicetree/bindings/memory-controllers/omap-gpmc.txt
-
-For the properties relevant to the ethernet controller connected to the GPMC
-refer to the binding documentation of the device. For example, the documentation
-for the SMSC 911x is Documentation/devicetree/bindings/net/smsc,lan9115.yaml
-
-Child nodes need to specify the GPMC bus address width using the "bank-width"
-property but is possible that an ethernet controller also has a property to
-specify the I/O registers address width. Even when the GPMC has a maximum 16-bit
-address width, it supports devices with 32-bit word registers.
-For example with an SMSC LAN911x/912x controller connected to the TI GPMC on an
-OMAP2+ board, "bank-width = <2>;" and "reg-io-width = <4>;".
-
-Required properties:
-- bank-width:          Address width of the device in bytes. GPMC supports 8-bit
-                       and 16-bit devices and so must be either 1 or 2 bytes.
-- compatible:          Compatible string property for the ethernet child device.
-- gpmc,cs-on-ns:       Chip-select assertion time
-- gpmc,cs-rd-off-ns:   Chip-select de-assertion time for reads
-- gpmc,cs-wr-off-ns:   Chip-select de-assertion time for writes
-- gpmc,oe-on-ns:       Output-enable assertion time
-- gpmc,oe-off-ns:      Output-enable de-assertion time
-- gpmc,we-on-ns:       Write-enable assertion time
-- gpmc,we-off-ns:      Write-enable de-assertion time
-- gpmc,access-ns:      Start cycle to first data capture (read access)
-- gpmc,rd-cycle-ns:    Total read cycle time
-- gpmc,wr-cycle-ns:    Total write cycle time
-- reg:                 Chip-select, base address (relative to chip-select)
-                       and size of the memory mapped for the device.
-                       Note that base address will be typically 0 as this
-                       is the start of the chip-select.
-
-Optional properties:
-- gpmc,XXX             Additional GPMC timings and settings parameters. See
-                       Documentation/devicetree/bindings/memory-controllers/omap-gpmc.txt
