refactor(neoverse-rd): set mmap naming convention

Presently, for the second generation platforms based on the N2 CPU,
macros related to page table entries lack a consistent naming
convention. This absence may lead to potential mix-ups, such as css
definitions in soc files, and can contribute to decreased code clarity.
To address this, establish the following naming convention:

- NRD_CSS_<name>_MMAP for CSS related page table entries
- NRD_ROS_<name>_MMAP for ROS related page table entries

refactor(neoverse-rd): refactor nrd_base_platform_def.h

The nrd_base_platform_def.h file includes CSS, RoS, firmware and
platform port related definitions. This approach of consolidating the
various definitions for multiple generation of platforms into the
nrd_base_platform_def.h file is not scaling well.

So in preparation of moving away from the use of nrd_base_platform_def.h
file for the second generation platforms based on N2/V2 CPUs, split the
definitions in this file into multiple include files. The new files into
which the definitions are refactored are -

- nrd_css_def2.h: includes CSS hardware related definitions
- nrd_css_fw_def2.h: includes CSS firmware related definitions
- nrd_ros_fw_def2.h: includes RoS firmware related definitions
- nrd_plat_arm_def2.h: includes platform port elated definitions

RoS (Rest Of System) is used to refer to the part of the reference
design platform that excludes CSS. The definitions that are only
relavant to the aforementioned platforms have been refactored from the
nrd_base_platform_def.h file.
