Subject: [PATCH 2/7] clk: mvebu: cp110: make failure labels more meaningful

In preparation to the addition of a new clock, rename the goto labels
used to handle the failure cases using a name related to the failure
cause. This will allow to insert additional failing cases without
renaming all the labels.
