feat(rdv3): enable numa aware per-cpu for RD-V3-Cfg2

RD-V3-Cfg2 being quad chip can make use of NUMA allocation within the
per-cpu framework. With NUMA allocation, the platform can distribute
per-cpu objects within a memory that is local to a particular node.
RD-V3-Cfg2 in this case has the per-cpu objects distributed across
different SRAMs present on the system.

introduce platform-specific helper functions to enhance the per_cpu
framework. Adds a helper function to zero init per_cpu sections,
ensuring clean initialization of per-cpu data. Introduces a function
to obtain the base address of per_cpu sections, facilitating efficient
access to per-CPU data structures. Enhances the per_cpu framework's
capability to handle platform-specific requirements.

These additions are crucial for maintaining the integrity and performance
of per-cpu operations.
