Subject: [PATCH v2 3/3] ata: ahci-xgene: Fix Wvoid-pointer-to-enum-cast warning

"version" is an enum, thus cast of pointer on 64-bit compile test with
clang W=1 causes:

  ahci_xgene.c:776:13: error: cast to smaller integer type 'enum xgene_ahci_version' from 'const void *' [-Werror,-Wvoid-pointer-to-enum-cast]
