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.

From Tegra186 onwards, the memory controller supports multiple channels.
Add support for mapping the address spaces of these channels and specify
the number of channels supported by Tegra186, Tegra194 and Tegra234.
In case of old bindings, channels won't be present. If channels are not
present then print a warning and continue so that backward compatibility
will be preserved in driver.
During error interrupts from memory controller, appropriate registers
from these channels need to be accessed for logging error info.
