Start DebugAgent from the beginning of Stage1B

Hardware Breakpoints must be used during CAR execution until
memory has been initiailzed for APL platform.

In order to use Hareware Breakpoints in UDK debugger, add
FlashRange in UDK config file and force to cover CAR area.
In SoftDebugger.ini of Windows UDK Debugger
Or In /etc/udkdebugger.conf of Linux UDK Debugger
  [Target System]
  FlashRange        = 0xFEF00000:0x1100000

Additionally,
  added Stage1BBase in STAGE1A_HOB
  fixed Stage1A module base report
