drivers: spi: add Data Fusion Subsystem SPI driver Introduce DesignWare ARC Data Fusion IP Subsystem(DFSS) SPI driver for ARC boards, i.e. EMSDP, which uses DW SPI to controll SPI-Flash and DFSS SPI to connect external devices. Both drivers share most source code, but DFSS uses ARC auxiliary registers. Move FIFO depth setting to device tree. Signed-off-by: Siyuan Cheng <siyuanc@synopsys.com>
