This new dbg() macro has the following features:
o Adds a '[USBSERIAL]' prefix to every debug message, that way usbserial
debug messages are not mixed up with other debug messages like kernel
timming information
o Also prints the function name (__FUNCTION__), that way dbg() calls
doesn't need to pass __FUNCTION__ as a parameter
Aditionally, the usb-serial and pl2303 drivers are ported to the new
interface.
