Tudor Ambarus 414d7b8c91 spi: s3c64xx: retrieve the FIFO depth from the device tree 
There are SoCs that configure different FIFO depths for their instances
of the SPI IP. See the fifo_lvl_mask defined for exynos4_spi_port_config
for example:
        .fifo_lvl_mask  = { 0x1ff, 0x7F, 0x7F },
The first instance of the IP is configured with 256 bytes FIFOs, whereas
the last two are configured with 64 bytes FIFOs.

Instead of mangling with the .fifo_lvl_mask and its dependency of the DT
alias ID, allow such SoCs to determine the FIFO depth via the
``fifo-depth`` DT property.
