[ Upstream commit 6c40624930c58529185a257380442547580ed837 ]

The Data Capture and Compare(DCC) is a debugging tool that uses the bootconfig
for configuring the register values during boot-time. Increase the max nodes
supported by bootconfig to cater to the requirements of the Data Capture and
Compare Driver.
