Move initialization of debugfs entries to a separate file. This simplifies the exclusion of the debugfs logic in the QAT driver when the kernel is built with CONFIG_DEBUG_FS=n. In addition, it will allow to consolidate the addition of debugfs entries to a single location in the code. This implementation adds infrastructure to create (and remove) debugfs entries at two different stages. The first, done when a device is probed, allows to keep debugfs entries persistent between a transition in device state (up to down or vice versa). The second, done after the initialization phase, allows to have debugfs entries that are accessible only when the device is up. In addition, move the creation of debugfs entries for configuration to the newly created function adf_dbgfs_init() and replace symbolic permissions with octal permissions when creating the debugfs files. This is to resolve the following warning reported by checkpatch: WARNING: Symbolic permissions 'S_IRUSR' are not preferred. Consider using octal permissions '0400'.
