soc: tegra: cbb: Add driver for Tegra234 CBB2.0

Adding driver to handle errors from CBB version 2.0 which is
used in Tegra234 SOC. The driver prints debug information about
failed transaction on receiving interrupt from Error Notifier.
Error notifier collates the interrupts from various Error
Monitor blocks and presents a single interrupt to the SOC
Interrupt Controller.
For timeout errors, the driver also does the lookup to find
timedout clients and prints client id. The IP's who want to
reset if there is a timeout will have to call BPMP from the
client IP's driver. BPMP firmware will also clear the timeout
bit after resetting the IP so that next transactions are send
to them after reset.
