Create unique TI RC for all reconfig loops

Creating a new TI RC (SHUTDOWN_DO_RECONFIG_LOOP = 0x513) that
will be used for all cases where HB is shutting down due to some
kind of hardware event with the expectation that the FSP will
execute a reconfig loop and start the IPL over.

Improved the SRC data for the error log that shows up when this
path is hit to include the potential reasons for the failure.
