Subject: [PATCH 4/4] ASoC: rockchip: Fix Wvoid-pointer-to-enum-cast warning

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

  rockchip_pdm.c:587:18: error: cast to smaller integer type 'enum rk_pdm_version' from 'const void *' [-Werror,-Wvoid-pointer-to-enum-cast]
