clk: mvebu: Off by one bugs in cp110_of_clk_get()
These > comparisons should be >= to prevent reading beyond the end of
of the clk_data->hws[] buffer.
The clk_data->hws[] array is allocated in cp110_syscon_common_probe()
when we do:
cp110_clk_data = devm_kzalloc(dev, sizeof(*cp110_clk_data) +
sizeof(struct clk_hw *) * CP110_CLK_NUM,
GFP_KERNEL);
As you can see, it has CP110_CLK_NUM elements which is equivalent to
CP110_MAX_CORE_CLOCKS + CP110_MAX_GATABLE_CLOCKS.
Fixes: d3da3eaef7f4 ("clk: mvebu: new driver for Armada CP110 system controller")
