Bluetooth: btusb: Configure Marvell to use one of the pins for oob wakeup

The Marvell devices may have many gpio pins, and hence for wakeup
on these out-of-band pins, the chip needs to be told which pin is
to be used for wakeup, using an hci command.

Thus, we read the pin number etc from the device tree node and send
a command to the chip.

-Marvell 8897/8997 (sd8897/sd8997) bluetooth SDIO devices
-------
-
-Required properties:
-
-  - compatible : should be one of the following:
-	* "marvell,sd8897-bt"
-	* "marvell,sd8997-bt"
-
-Optional properties:
-
-  - marvell,cal-data: Calibration data downloaded to the device during
-		      initialization. This is an array of 28 values(u8).
-
-  - 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-parent: phandle of the parent interrupt controller
-  - interrupts : interrupt pin number to the cpu. 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 condition. 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.
-calibration data is also available in below example.
