dt-bindings: net: add TI CC2560 Bluetooth chip

This adds a compatible string for the Texas Instruments CC2560 Bluetooth
chip to the existing TI WiLink shared transport bindings. These chips are
similar enough that the same bindings work for both. The file is renamed
to ti-bluetooth.txt to make it more generic.

-TI WiLink 7/8 (wl12xx/wl18xx) Shared Transport BT/FM/GPS devices
-
-TI WiLink devices have a UART interface for providing Bluetooth, FM radio,
-and GPS over what's called "shared transport". The shared transport is
-standard BT HCI protocol with additional channels for the other functions.
-
-These devices also have a separate WiFi interface as described in
-wireless/ti,wlcore.txt.
-
-This bindings follows the UART slave device binding in
-../serial/slave-device.txt.
-
-Required properties:
- - compatible: should be one of the following:
-    "ti,wl1271-st"
-    "ti,wl1273-st"
-    "ti,wl1281-st"
-    "ti,wl1283-st"
-    "ti,wl1285-st"
-    "ti,wl1801-st"
-    "ti,wl1805-st"
-    "ti,wl1807-st"
-    "ti,wl1831-st"
-    "ti,wl1835-st"
-    "ti,wl1837-st"
-
-Optional properties:
- - enable-gpios : GPIO signal controlling enabling of BT. Active high.
- - vio-supply : Vio input supply (1.8V)
- - vbat-supply : Vbat input supply (2.9-4.8V)
- - clocks : Must contain an entry, for each entry in clock-names.
-   See ../clocks/clock-bindings.txt for details.
- - clock-names : Must include the following entry:
-   "ext_clock" (External clock provided to the TI combo chip).
- - nvmem-cells: phandle to nvmem data cell that contains a 6 byte BD address
-   with the most significant byte first (big-endian).
- - nvmem-cell-names: "bd-address" (required when nvmem-cells is specified)
-
