Subject: [PATCH 3/4] mmc: jz4740: Fix Wvoid-pointer-to-enum-cast warning

"jz4740" is an enum, thus cast of pointer on 64-bit compile test with
clang W=1 causes:

  jz4740_mmc.c:1055:18: error: cast to smaller integer type 'enum jz4740_mmc_version' from 'const void *' [-Werror,-Wvoid-pointer-to-enum-cast]
