[PATCH] ide: fix crash at boot with siimage driver

[Benjamin Herrenschmidt <benh@kernel.crashing.org>]

Some change to the IDE layer are causing the siimage driver to crash
at boot with a NULL dereference. This is due to the sil_dma_ops not
containing all the necessary pointers. I suppose it used to just
"override" the defaults while now, it needs to contain everything.
