arm64: tegra: Update AHUB clock parent and rate

Browse Source 
I2S data sanity test failures are seen at lower AHUB clock rates
on Tegra234. The Tegra194 uses the same clock relationship for AHUB
and it is likely that similar issues would be seen. Thus update the
AHUB clock parent and rates here as well for Tegra194, Tegra186
and Tegra210.
