spi: spi-ep93xx: use read,write instead of __raw_* variants
spi: spi-ep93xx: use bits_per_word_mask
spi: spi-ep93xx: always handle transfer specific settings
spi: spi-ep93xx: remove bits_per_word() helper
spi: spi-ep93xx: remove 'dss' from per chip private data
spi: spi-ep93xx: don't bother calculating the divisors in ep93xx_spi_setup()
spi: spi-ep93xx: move the clock divider calcs into ep93xx_spi_chip_setup()
spi: spi-ep93xx: convert to the queued driver infrastructure
