dt-bindings: net: Convert Marvell 8897/8997 bindings to DT schema

Convert the existing text-based DT bindings for Marvell 8897/8997
(sd8897/sd8997) bluetooth devices controller to a DT schema.

While here, bindings for "usb1286,204e" (USB interface) are dropped from
the DT schema definition as these are currently documented in file [0].

-Marvell 8897/8997 (sd8897/sd8997) bluetooth devices (SDIO or USB based)
-------
-The 8997 devices supports multiple interfaces. When used on SDIO interfaces,
-the btmrvl driver is used and when used on USB interface, the btusb driver is
-used.
-
-Required properties:
-
-  - compatible : should be one of the following:
-	* "marvell,sd8897-bt" (for SDIO)
-	* "marvell,sd8997-bt" (for SDIO)
-	* "usb1286,204e"      (for USB)
-
-Optional properties:
-
-  - marvell,cal-data: Calibration data downloaded to the device during
-		      initialization. This is an array of 28 values(u8).
-		      This is only applicable to SDIO devices.
-
-  - marvell,wakeup-pin: It represents wakeup pin number of the bluetooth chip.
-		        firmware will use the pin to wakeup host system (u16).
-  - marvell,wakeup-gap-ms: wakeup gap represents wakeup latency of the host
-		      platform. The value will be configured to firmware. This
-		      is needed to work chip's sleep feature as expected (u16).
-  - interrupt-names: Used only for USB based devices (See below)
-  - interrupts : specifies the interrupt pin number to the cpu. For SDIO, the
-		 driver will use the first interrupt specified in the interrupt
-		 array. For USB based devices, the driver will use the interrupt
-		 named "wakeup" from the interrupt-names and interrupt arrays.
-		 The driver will request an irq based on this interrupt number.
-		 During system suspend, the irq will be enabled so that the
-		 bluetooth chip can wakeup host platform under certain
-		 conditions. During system resume, the irq will be disabled
-		 to make sure unnecessary interrupt is not received.
-
-Example:
-
-IRQ pin 119 is used as system wakeup source interrupt.
-wakeup pin 13 and gap 100ms are configured so that firmware can wakeup host
-using this device side pin and wakeup latency.
-
-Example for SDIO device follows (calibration data is also available in
-below example).

-	vmmc-supply = <&wlan_en_reg>;
-	bus-width = <4>;
-	cap-power-off-card;
-	keep-power-in-suspend;

-	#size-cells = <0>;
-	btmrvl: bluetooth@2 {

-		marvell,wakeup-pin = /bits/ 16 <0x0d>;
-		marvell,wakeup-gap-ms = /bits/ 16 <0x64>;
-	};

-Example for USB device:
-
-&usb_host1_ohci {
-    #address-cells = <1>;
-    #size-cells = <0>;
-
-    mvl_bt1: bt@1 {

-	interrupt-parent = <&gpio0>;
-	interrupt-names = "wakeup";
-	interrupts = <119 IRQ_TYPE_LEVEL_LOW>;

-	marvell,wakeup-gap-ms = /bits/ 16 <0x64>;
