ASoC: rockchip: Fix Wvoid-pointer-to-enum-cast warning (again)

[ Upstream commit 57d508b5f718730f74b11e0dc9609ac7976802d1 ]

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

  rockchip_pdm.c:583:17: error: cast to smaller integer type 'enum rk_pdm_version' from 'const void *' [-Werror,-Wvoid-pointer-to-enum-cast]

This was already fixed in commit 49a4a8d12612 ("ASoC: rockchip: Fix
Wvoid-pointer-to-enum-cast warning") but then got bad in
commit 9958d85968ed ("ASoC: Use device_get_match_data()").

Discussion on LKML also pointed out that 'uintptr_t' is not the correct
type and either 'kernel_ulong_t' or 'unsigned long' should be used,
with several arguments towards the latter [1].
