ALSA: hda/tegra: Update scratch reg. communication
Tegra234 chip scratch register communication between audio
and hdmi driver differs slightly in the way it triggers the
interrupt compared to legacy chips. Interrupt is triggered
by writing non-zero values to verb 0xF80 instead of 31st bit
of scratch register.
DP MST support changed the NID to be used for scratch register
read/write from audio function group NID to Converter widget NID.
