This patch replaces the calls to printk(KERN_DEBUG ...) with either calls to xhci_dbg() or calls to pr_debug(), depending on whether the xhci_hcd structure is available at callsite, so that the correspoding debugging messages are not enabled by default when CONFIG_DYNAMIC_DEBUG option is set but rather can be enabled dynamically taking advantage of the dynamic debugging feature. Also, it adds a newline at the end of debugging messages in case there is not, so that messages don't appear broken when printed.
