USB: musb: make DBG() calls actually depend on CONFIG_USB_MUSB_DEBUG
Enabling CONFIG_USB_MUSB_DEBUG option causes -DDEBUG to be added to gcc's
command line, however the DBG() macro doesn't depend on DEBUG, so that the
debugging messages get printed regardless of the option, and I don't think
that this was intended. Get rid of otherwise unused xprintk() macro and make
DBG() macro directly call pr_debug() which only results in the actual code
generated if DEBUG is defined.
This change makes musb_hdrc.o ~30% less in size with CONFIG_USB_MUSB_DEBUG
disabled (in host mode).
