Why?  These properties mean different things - num-cs is a bit confused
and is the total number of available chip selects for the system (which
could include GPIOs) while num-ss-bits is the size of the bitfield
(which could include things not actually mapped out properly/successfully 
or something if the hardware designers were feeling particularly inspired).

I'm not convinced num-cs ever made any sense.
