Bluetooth: Remove Enter/Leave debug statements from Marvell driver
The Marvell Bluetooth driver is full of Enter/Leave debug statements and all of them are really pointless and only clutter the code. Seems to be some left-overs when they ported the driver from Windows. For the Linux driver lets remove these. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
