Commit c045ceb5a145 ("reset: tegra-bpmp: Handle errors in BPMP
response") fixed an issue in the Tegra BPMP error handling but has
exposed an issue in the Tegra194 HDA driver and now resetting the
Tegra194 HDA controller is failing. For now revert the commit
c045ceb5a145 ("reset: tegra-bpmp: Handle errors in BPMP response")
while a fix for the Tegra HDA driver is created.
