Now that qcom_cc_remove() is a nop, drop calls to
qcom_cc_remove() and any empty driver remove functions.

And here's the driver part. I left 8960_remove in place to make your patch
easier to apply. Time to sleep.

I was trying to test this out, but looks like none of our clock drivers
support a clean remove and reprobe (with or without this patch)

The problem seems to be the fixed rate clocks that get registered at probe,
never unregistered, causing the subsequent probe to fail.

Yeah the gcc drivers are not so good there. We should probably fix those too.

The mmcc drivers support a clean remove and reprobe though. So I
tested it on msm8960 with these patches and everything looks
good. Removing gcc is sort of annoying because it provides the
clock for the serial console.
