This compile issue when spi config was set as module then
"loongson_spi_dev_pm_ops undefined" will occur, but if set spi config as
built-in and not this issue, and my patch was tested that use spi config
built-in so not this error occur, and this compile fail issue's reason
was "loongson_spi_dev_pm_ops" not use EXPORT_SYMBOL_GPL to export, I
will add following change to fix this compile error issue.
