clk: mvebu: armada-37xx-periph: Fix wrong return value in get_parent
The return value of the get_parent operation is a u8, whereas a -EINVAL was returned. This wrong value was return if the value was bigger that the number of parent but this case was already handled by the core. So we can just remove this chunk of code to fix the issue.
