Decouple V2M_SYS config by auto-detect dtb node
An auto-detect switch is added to make it an option to enable/disable
'arm,vexpress-sysreg', because not all platforms support this feature.
But the auto-detection generates the side-effect of printing a warning
message about the missing node:
No matching devices found at ./findbase.pl line 37.
In this case, to drop the warning message, add "2> /dev/null" at the
end of the findbase.pl call.
