ata: sata_rcar: Fix compilation warning

Browse source 
When compiling with clang and W=1, the following warning is generated:

drivers/ata/sata_rcar.c:878:15: error: cast to smaller integer type
'enum sata_rcar_type' from 'const void *'
[-Werror,-Wvoid-pointer-to-enum-cast]
        priv->type = (enum sata_rcar_type)of_device_get_match_data(dev);
                     ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Fix this by using a cast to unsigned long to match the "void *" type
size returned by of_device_get_match_data().
