usb: musb: get rid of MUSB_LOGLEVEL and use parameter 

We can change debugging level on the fly via
/sys/module/musb_hdrc/parameters/debug.

We can also get rid of the LOGLEVEL facility in Kconfig
and rely only in module parameter.

Set the logging level. 0 disables the debugging altogether,
although when USB_DEBUG is set the value is at least 1.
Starting at level 3, per-transfer (urb, usb_request, packet,
or dma transfer) tracing may kick in.
This enables musb debugging. To set the logging level use the debug
module parameter. Starting at level 3, per-transfer (urb, usb_request,
packet, or dma transfer) tracing may kick in.
