ata: ahci_brcm: Fix compilation warning 

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

drivers/ata/ahci_brcm.c:451:18: error: cast to smaller integer type
'enum brcm_ahci_version' from 'const void *'
[-Werror,-Wvoid-pointer-to-enum-cast]
        priv->version = (enum brcm_ahci_version)of_id->data;
                        ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

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