    Compiling the hdac extended core on arm fails with below error:
    
      sound/hda/ext/hdac_ext_bus.c: In function 'hdac_ext_writel':
    >> sound/hda/ext/hdac_ext_bus.c:29:2: error: implicit declaration of
    >> function
    +'writel' [-Werror=implicit-function-declaration]
         writel(value, addr);
         ^
       sound/hda/ext/hdac_ext_bus.c: In function 'hdac_ext_readl':
    >> sound/hda/ext/hdac_ext_bus.c:34:2: error: implicit declaration of
    >> function
    +'readl' [-Werror=implicit-function-declaration]
         return readl(addr);
    
    This is fixed by explicitly including io.h
