spi: Fixes for v4.1

Browse source 
A number of driver specific fixes (including several missing
 dependencies for randconfig type cases) plus two core fixes.  One makes
 the setup_transfer() callback optional which unbreaks some drivers which
 had been merged with it omitted due to local versions of this patch and
 another ensures that we don't corrupt data by leaking internal dummy
 buffers to callers, causing the callers to think they allocated those
 buffers.
