Nathan E. Egge 8280ec7a32 lavu/riscv: Revert d808070, removing AV_READ_TIME 
The implementation of ff_read_time() for RISC-V uses rdtime which has
 precision on existing hardware too low (!) for benchmarking purposes.
Deleting this implementation falls back on clock_gettime() which was
 added as the default ff_read_time() implementation in 33e4cc9.
Below are metrics gathered on SpacemiT K1, before and after this commit:
