As DCC is not going to be enabled on secure device,
SDI would dump required registers in standard dcc dumping format.
So extend ramparser’s DCC parsing support for <address><value> format.
The KMISC section would contain all registers address value pair as mentioned below.
Parse the data and generate the “dcc_captured_data.xml” and it should be same as actual dcc dump parsed xml.
