Sumit Gupta 7d6370223d soc/tegra: cbb: Check firewall before enabling error reporting 
[ Upstream commit 2927cf85f4 ]

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.
