[PATCH v2 12/25] kernel/configs: Register dynamic information into meminspect

[Mukesh Ojha]

From: Eugen Hristev <eugen.hristev@xxxxxxxxxx>

Register kernel_config_data information into inspection table.
Debugging tools look for the start and end markers, so we need to
capture those as well into the region.
