[PATCH v3 2/3] spi: s3c64xx: prioritize fifo-depth from DT over port_config

[Denzeel Oliva <wachiturroxd150@gmail.com>]

Rearrange s3c64xx_spi_probe() to ensure that the 'fifo-depth' property
from the device tree (DT) is always prioritized over the fallback
values in port_config.

Previously, if port_config had a fifo_depth value, it would override
the DT property. This prevented DT from correctly setting the depth
per node.

This ensures flexibility for device tree configurations while keeping
a safe fallback.
