memory: tegra: Add MC error logging on Tegra186 onward
Add support for logging memory controller errors on Tegra186, Tegra194
and Tegra234. On these SoCs, interrupts can occur on multiple channels.
Add support required to read the status of interrupts across multiple
channels, log and clear them.
Also add new interrupts supported on these SoCs.
