lockdep: Clarify size for LOCKDEP_*_BITS configs
The LOCKDEP_*_BITS configs control the size of internal structures used
by lockdep. The size is calculated as a power of two of the configured
value (e.g. 16 => 64KB). Update these descriptions to more accurately
reflect this, as "Bitsize" can be misleading.
