I really don't want to keep going through the pain with having people
constantly adding access for chip select that bypass the helpers if we
can avoid it, there's been a constant need for fixups which have just
added to the pain with the multi CS stuff.  My thinking was to get the
API in place and then improve the implementation behind it.
