The SPI module in Exynos 5420 didn't follow Coreboot's SPI API standard
(spi-generic.h) and will be a problem when we want to share SPI drivers.
This commit replaces exynos_spi_* by spi_* functions.
Note, exynos_spi_read is kept and changed to a static function because its usage
is different from the standard API "spi_xfer".
