[PATCH resend] powerpc/vdso64: Add support for CLOCK_{REALTIME/MONOTONIC}_COARSE

Current vDSO64 implementation does not have support for coarse clocks (CLOCK_MONOTONIC_COARSE, CLOCK_REALTIME_COARSE), for which it falls back to system call, increasing the response time, vDSO implementation reduces the cycle time. Below is a benchmark of the difference in execution time with and
