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

drivers/ata/ahci_xgene.c:788:14: error: cast to smaller integer type
'enum xgene_ahci_version' from 'const void *'
[-Werror,-Wvoid-pointer-to-enum-cast]
       version = (enum xgene_ahci_version) of_devid->data;
                 ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Fix this by using a cast to unsigned long to match the "void *" type
size of of_devid->data.
