Sandeep Paulraj cc36e97b0b DaVinci: DM365: Add Support for new Revision of silicon 
DM365 RBL has been updated. The variant number has changed for this
new revision of silicon. This patch adds support for the
new revision of DM365.
The name fields are also being updated to reflect the version
of the silicon.

Without this minor fix DM365 REV 1.2 will not boot up
