refactor(neoverse-rd): remove soc_css.mk from common makefile
The soc_css.mk file within the plat/arm/soc module currently implements
initialization functions for the PCIe controller and NIC400 within the
SOC specification. However, as none of the Neoverse reference design
platforms necessitate the initialization of PCIe or NIC400, remove the
soc_css.mk from the common makefile.
Additionally, empty initialization functions for PCIe and NIC400 are
added to satisfy the requirements of the plat/arm common code, which
expects these functions to be present.

refactor(neoverse-rd): move defines out of platform_def.h
Presently, the second generation platforms have direct references to CSS
and ROS specific addresses within RD-N2's platform header file
(platform_def.h). Moreover, there are platform port specific macros
defined within platform_def.h To enhance organization and
appropriateness, relocate these definitions to nrd_css_def2.h,
nrd_ros_def2.h and nrd_arm_platform_def1.h files accordingly. Reuse
these definitions within the platform_def.h files as needed.
Additionally, remove reference to the unused PLAT_ARM_GICC_BASE macro
from the individual platform_def.h file.

refactor(neoverse-rd): add defines for ROM, SRAM and DRAM2
In the current setup, the base and size of the ROM, SRAM, and DRAM2
regions are directly defined in the nrd_fw_def2.h file for N2 CPU based
platforms. To enhance modularity and appropriateness, introduce macros
for these definitions in the respective css file (nrd_css_def2.h). While
the maximum sizes for ROM, SRAM, and DRAM2 are specified in the css
specification, the actual implementation sizes may vary. Consequently,
relocate the size macros to the platform-specific platform_def.h file
for individual platforms.

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.
