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.
