spi: add SPI controller driver for UniPhier SoC
Add SPI controller driver implemented in Socionext UniPhier SoCs. UniPhier SoCs have two types SPI controllers; SCSSI supports a single channel, and MCSSI supports multiple channels. This driver supports SCSSI only. This controller has 32bit TX/RX FIFO with depth of eight entry, and supports the SPI master mode only. This commit is implemented in PIO transfer mode, not DMA transfer.
