soc/tegra: cbb: Remove MODULE_LICENSE in non-modules
Since commit 8b41fc4454e ("kbuild: create modules.builtin without
Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations
are used to identify modules. As a consequence, uses of the macro
in non-modules will cause modprobe to misidentify their containing
object file as a module when it is not (false positives), and modprobe
might succeed rather than failing with a suitable error message.
So remove it in the files in this commit, none of which can be built as
modules.

soc/tegra: cbb: Check firewall before enabling error reporting
To enable error reporting for a fabric to CCPLEX, we need to write its
register for enabling error interrupt to CCPLEX during boot and later
clear the error status register after error occurs. If a fabric's
registers are protected and not accessible from CCPLEX, then accessing
the registers will cause CBB firewall error.
Add support to check whether write access from CCPLEX to the registers
of a fabric is not blocked by it's firewall before enabling error
reporting to CCPLEX for that fabric.

Adding support for Tegra241 (Grace) which uses fabrics based on the CBB
2.0 architecture. Since Tegra241 requires ACPI, implement ACPI-based
probe support.
Fabrics reporting errors in Tegra241 are "CBB" and "BPMP". The CBB
fabric connects various other CBB 2.0 based fabrics and also services
the Initiators and Targets which are connected to itself. The BPMP
fabric is present in the BPMP cluster.

soc/tegra: cbb: Add driver for Tegra234 CBB 2.0
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 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.
