Subject: [PATCH net-next 2/2] wifi: ath10k: fix Wvoid-pointer-to-enum-cast warning

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

  ath10k/ahb.c:736:11: error: cast to smaller integer type 'enum ath10k_hw_rev' from 'const void *' [-Werror,-Wvoid-pointer-to-enum-cast]
