Currently, CONFIG_SPL_SPI_* #defines are used for controlling SPI boot in SPL. These #defines do not allow the user to select SPI mode for the SPI flash (there's no CONFIG_SPL_SPI_MODE, so the SPI mode is hardcoded in spi_spl_load.c), and duplicate information already provided by CONFIG_SF_DEFAULT_* #defines. Kill CONFIG_SPL_SPI_*, and use CONFIG_SF_DEFAULT_* instead.
