Subject: [PATCH v4 04/16] spi: dw: Discard unused void priv pointer

Seeing the "void *priv" member of the dw_spi data structure is unused
let's remove it. The glue-layers can embed the DW APB SSI controller
descriptor into their private data object. MMIO driver for instance
already utilizes that design pattern.
