[PATCH 2/6] binman: x509_cert: allow and parse distinguished-name subnode

[Rasmus Villemoes <ravi@prevas.dk>]

Currently, the ti-secure and ti-secure-rom types hardcode the contents
of the Distinguished Name section. Those values are not necessarily
appropriate for all boards that just happen to include a SOC produced
by TI.

Allow placing a distinguished-name subnode inside the binman node
representing the Entry_x509_cert (or derived classes), and if present,
use that information.
