intel: Implement platform specific system reset 2
Add support for platform specific warm-reset through psci system reset 2.
- system_reset2 implementation that calls for l2 cache reset
- Check for magic number and request for warm reset in bl2
- Create a shared reset manager header file for Agilex and Stratix 10
- Clean up parameter info in plat_get_next_bl_params
