spi: Add SiFive SPI driver This patch adds SiFive SPI driver. The driver is 100% DM driver and it determines input clock using clk framework. The SiFive SPI block is found on SiFive FU540 SOC and is used to access flash and MMC devices on SiFive Unleashed board. This driver implementation is inspired from the Linux SiFive SPI driver available in Linux-5.2 or higher and SiFive FSBL sources.
