arm: socfpga: Move Stratix10 and Agilex reset manager common code
Move Stratix10 and Agilex reset manager common code to reset_manager_soc64.h. Changed macros to RSTMGR_SOC64_*. Remove unused RSTMGR_XXX defines. Signed-off-by: Ley Foon Tan <ley.foon.tan@intel.com> Reviewed-by: Simon Goldschmidt <simon.k.r.goldschmidt@gmail.com>
