[PATCH v2 05/28] spi: dt-bindings: samsung: add samsung,spi-fifosize property

[Tudor Ambarus <tudor.ambarus@xxxxxxxxxx>]

Up to now the SPI alias was used as an index into an array defined in
the SPI driver to determine the SPI FIFO size. Drop the dependency on
the SPI alias and allow the SPI nodes to specify their SPI FIFO size.
