spi: hisi-kunpeng: Fixed the wrong debugfs node name in hisi_spi debugfs initialization

commit 9c04e8a224613f439d43cda9afe487e6a0702040 openEuler

in hisi_spi_debugfs_init, spi controller pointer is calculated by
container_of macro, and the member is hs->dev. But the host pointer cannot
be calculated offset directly by this, because hs->dev points to the
device in platform device(pdev->dev), and the host->dev points to the
pdev->dev.parent.

In this patch, this issues is fixed by getting the controller data
from pdev->dev.driver_data directly, driver_data points to the spi
controller data in the probe stage.
