Subject: [PATCH 5/7] mtd: rawnand: vf610: Fix Wvoid-pointer-to-enum-cast warning

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

  vf610_nfc.c:843:17: error: cast to smaller integer type 'enum vf610_nfc_variant' from 'const void *' [-Werror,-Wvoid-pointer-to-enum-cast]
