In further patches, we aim to enable -Wredundant-decls by default. This rearragement of helper macros is necessary to make Coverity tool happy as well as making sure there are no redundant function declarations for PMF related declarations. Also, PMF related macros were added to provide appropriate function declarations for helper APIs which capture PSCI statistics.
