refactor(qemu-sbsa): move DT related structures to their own header

Browse source 
Move structure declaration related to the DT to their own header.  That
way they can be reused by other files.  At the same time, typedefs are
removed and structure names prepended with "platform_" to avoid clashing
with other structure declarations available in the system.

No change in functionality.
