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.
