clk: mvebu: armada-37xx-periph: Fix the clock provider registration
While trying using a peripheral clock on a driver, I saw that the clock pointer returned by the provider was NULL. The problem was a missing indirection. It was the pointer stored in the hws array which needed to be updated not the value it contains.
