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 specify the SPI FIFO size directly into the SPI node.
The FIFO sizes were determined based on the SPI aliases that are defined
in exynos5433-tm2-common.dtsi.
