struct ti_qspi_priv->max_hz is declared as unsigned int, so the following
error path check will always be false, even when "spi-max-frequency"
property is invalid/missing:
priv->max_hz = fdtdec_get_int(blob, node, "spi-max-frequency", -1);
if (priv->max_hz < 0) {
...
}
Replace the fdtdec call with dev_read_u32_default() and use 0 as the
default value. Error out if max_hz is zero.
