Will Deacon 85044eb08d of: Return success from of_dma_set_restricted_buffer() when !OF_ADDRESS 
When CONFIG_OF_ADDRESS=n, of_dma_set_restricted_buffer() returns -ENODEV
and breaks the boot for sparc[64] machines. Return 0 instead, since the
function is essentially a glorified NOP in this configuration.
