This series adds support for SPI controller driver implemented on UniPhier SoCs.

Changes since v1:
- modify not to config SPI in master->setup method.
- fix internal bug of uniphier_spi_fill_tx_fifo().
- replace macro of BYTES_PER_WORD to inline function.
- use IRQ_NONE in irq handler.
- modify the handling of word size in uniphier_spi_send() and uniphier_spi_recv().
- modify help in Kconfig.
- other trivial change.
