riscv: Split out measure_cycles() for reuse

Browse source

Byte cycle measurement and word cycle measurement of scalar misaligned
access are very similar. Split these parts out into a common
measure_cycles() function to avoid duplication.

This function will also be reused for vector misaligned access probe in a
follow-up commit.
