By modifying the soc.clock_limits[n] struct directly, this can cause unintended behavior as the for loop attempts to swap rows in clock_limits[n]. A temporary struct is still required to make sure we stay functinoally equivalent. [How] Add a temporary clock_limits table to the SOC struct, and use it when swapping rows.
