sound: Add delay.h to sound/soc/codecs/sn95031.c
sound: Add delay.h to sound/soc/codecs/sn95031.c

This is further fallout from delay.h removal from asm/apic.h and asm/dma.h:

  ca444564a947: x86: Stop including <linux/delay.h> in two asm header files

Which caused this build failure:

  sound/soc/codecs/sn95031.c: In function ‘sn95031_get_mic_bias’:
  sound/soc/codecs/sn95031.c:153:2: error: implicit declaration of function ‘msleep’ [-Werror=implicit-function-declaration]
