Subject: [PATCH v2 2/3] ata: ahci-imx: Fix Wvoid-pointer-to-enum-cast warning

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

  ahci_imx.c:872:18: error: cast to smaller integer type 'enum ahci_imx_type' from 'const void *' [-Werror,-Wvoid-pointer-to-enum-cast]
