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].
* DT binding users are updated to use bluetooth generic name
recommendation.

-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).
