Subject: [PATCH net-next] reset: hisilicon: hi6220: fix Wvoid-pointer-to-enum-cast warning

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

hi6220_reset.c:166:9: error: cast to smaller integer type 'enum hi6220_reset_ctrl_type' from 'const void *' [-Werror,-Wvoid-pointer-to-enum-cast]
