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 the error notifier. The 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 timed out
clients and prints their client ID. Drivers for hardware that needs to
be reset on 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.

Adding driver to handle errors from Control Backbone (CBB) which are
generated due to illegal accesses. CBB 1.0 is used in Tegra194 SoCs.
When an error is reported from a NOC within CBB, the driver prints debug
information about failed transaction like Error Code, Error Description,
Master, Address, AXI ID, Cache, Protection, Security Group etc. It then
causes system crash using BUG_ON() or call WARN() based on whether the
error type is fatal or not.
