powerpc/mpic: Search for open-pic device-tree node if NULL
Almost all PowerPC platforms use a standard "open-pic" device node so the mpic_alloc() function now accepts NULL for the device-node. This will cause it to perform a default search with of_find_matching_node(). Signed-off-by: Kyle Moffett <Kyle.D.Moffett@boeing.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
