Subject: [PATCH 5/7] ARM: dts: samsung: exynos5450: specify the SPI fifosize

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.

Hi Tudor,

There is a typo in the subject of this patch, exynos 5450 instead of
5420. Maybe that is something krzk can fix when applying.

Best regards,
