[PATCH AUTOSEL 4.18 119/131] ALSA: ad1816a: Fix sparse warning wrt PCM format type

[ Upstream commit d63f33d3f083bdb3a7c2dfd623f4d811b2a8d772 ]
The PCM format type is with __bitwise, and it can't be converted from
integer implicitly. Instead of an ugly cast, declare the function
argument of snd_ad1816a_get_format() with the proper snd_pcm_format_t
type.
This fixes the sparse warning like:
