    snd_hda: fix attaching to some AMD Radeon GPUs
    
    HDMI audio did not work on my older Radeon GPU, the error message
    during attach was:
    
    hdac0: hdac_get_capabilities: Invalid corb size (0)
    
    This is fixed by calling hdac_reset() before the HDA device
    capabilities are retrieved. This solution was proposed by Andriy Gapon
    in 2010, but apparently did not solve the problem reported at the time.
