staging: axis-fifo: refactor device tree parsing

Refactor the device tree parsing logic in axis_fifo_probe() to reduce
verbosity and simplify error handling.

Remove the verbose error logging and goto logic. Instead, check
of_property_read_u32() return values directly and propagate error codes
immediately. This aligns the driver with modern kernel standards by
removing unnecessary error messages during probe.
