[PATCH 4/4] rtc: rs5c372: fix Wvoid-pointer-to-enum-cast warning

[Krzysztof Kozlowski]

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

  rtc-rs5c372.c:829:19: error: cast to smaller integer type 'enum rtc_type' from 'const void *' [-Werror,-Wvoid-pointer-to-enum-cast]
