[PATCH] ASoC: mediatek: mt8365: include linux/bitfield.h

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

On x86, the header is not already included implicitly,
breaking compile-testing:

In file included from sound/soc/mediatek/mt8365/mt8365-afe-common.h:19,
                 from sound/soc/mediatek/mt8365/mt8365-afe-pcm.c:18:
sound/soc/mediatek/mt8365/mt8365-afe-pcm.c: In function 'mt8365_afe_cm2_mux_conn':
sound/soc/mediatek/mt8365/mt8365-reg.h:952:41: error: implicit declaration of function 'FIELD_PREP' [-Wimplicit-function-declaration]
  952 | #define CM2_AFE_CM2_CONN_CFG1(x)        FIELD_PREP(CM2_AFE_CM2_CONN_CFG1_MASK, (x))
      |                                         ^~~~~~~~~~

Included it ahead of the field definitions.

Fixes: 38c7c9ddc740 ("ASoC: mediatek: mt8365: Add common header")

This started happening after I applied "ASoC: mt8365: Allow build coverage".
