xhci: remove CONFIG_USB_XHCI_HCD_DEBUGGING and unused code
CONFIG_USB_XHCI_HCD_DEBUGGING option is used to enable verbose debugging output for the xHCI host controller driver. In the current version of the xhci-hcd driver, this option must be turned on, in order for the debugging log messages to be displayed, and users may need to recompile the linux kernel to obtain debugging information that will help them track down problems. This patch removes the above debug option to enable debugging log messages at all times. The aim of this is to rely on the debugfs and the dynamic debugging feature for fine-grained management of debugging messages and to not force users to set the debug config option and compile the linux kernel in order to have access in that information. This patch, also, removes the XHCI_DEBUG symbol and the functions dma_to_stream_ring(), xhci_test_radix_tree() and xhci_event_ring_work() that are not useful anymore.
