Revert "ns16650: Make sure we have CONFIG_CLK set before using infrastructure" 

This reverts commit 82f5279b0c.

The build failure of k2*evm boards was fixed in a different way by
the previous commit.  It is nasty to patch generic drivers around
with #ifdef CONFIG_CLK just for the KeyStone's matter.
