locking/csd_lock: Add Kconfig option for csd_debug default
The csd_debug kernel parameter works well, but is inconvenient in cases where it is more closely associated with boot loaders or automation than with a particular kernel version or release. Thererfore, provide a new CSD_LOCK_WAIT_DEBUG_DEFAULT Kconfig option that defaults csd_debug to 1 when selected and 0 otherwise, with this latter being the default. Signed-off-by: Paul E.
