On Exynos9610, only TOP pinctrl doesn't have a clock (as far as I'm
aware; haven't found a clock for it), while the rest of the pin controller
blocks do.

The first message is the commit message, and the second one is the b4
cover message. I wasn't actually sure how b4 handles that.

AFAIK there are no (publicly available) users of this device, so this
change shouldn't break any currently available device trees.

The best (most correct imo) implementation would be having the clock
properties be optional, pin controllers for Exynos9610 don't need
to be controlled by Linux for suspend/restore (change is more for
information(?) correctness anyway), since the CMUs should have HWACG
enabled anyway.
