Using the addi-data "common" code in addi_apci_1564 introduces a lot of
bloat.  By separating this driver off from addi_common.c, a lot of the
common code can be stripped out.  This patch copies the code over from
addi_common.c, and removes the #include of the file.  The auto_attach
function from the common code replaces the one that was previously in this
driver, though renamed to that it stays within the namespace associated
with this driver, and the detach function has been renamed for this reason
as well.

This patch replaces rcu_assign_pointer(x, NULL) with RCU_INIT_POINTER(x, NULL)

The rcu_assign_pointer() ensures that the initialization of a structure
is carried out before storing a pointer to that structure.
And in the case of the NULL pointer, there is no structure to initialize.
So, rcu_assign_pointer(p, NULL) can be safely converted to RCU_INIT_POINTER(p, NULL)
