isci: unify constants
cross driver constants are spread out over multiple header files, consolidate them into isci.h, and push some includes out to the source files that need them. TODO: remove SCI_MODE_SIZE infrastructure. TODO: task.h is full of inlines that are too large Signed-off-by: Dan Williams <dan.j.williams@intel.com>
