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.
