drm/v3d: Correct clock settng calls to new APIs

There was a report that 6.12 kernel has lower benchmark
scores than 6.6.

I can confirm, and found it started with 6.8 kernel
which moved some code into a new file (v3d_submit.c)
and in two places the change to the clock api were missed.

The effect of the bug is the v3d clock sometimes
unwantedly drops to a lower rate.

With this patch the benchmark scores are good again.
