Subject: [PATCH v2 21/28] spi: s3c64xx: infer fifosize from the compatible

Infer the FIFO size from the compatible, where all the instances of the
SPI IP have the same FIFO size. This way we no longer depend on the SPI
alias from the device tree to select the FIFO size, thus we remove the
dependency of the driver on the SPI alias.
