refactor(neoverse-rd): define naming convention for RoS macros

As part of the refactoring for the second generation platforms,
introduce a naming convention for macros within nrd_ros_def2.h and
nrd_ros_fw_def2.h.  All macros, except those related to page table
entries, must adhere to the format NRD_ROS_<name>. Page table entry
macros are handled separately and are not part of this patch.
