clk: sunxi-ng: common: Don't call hw_to_ccu_common on hw without common

In the Linux kernel, the following vulnerability has been resolved:

clk: sunxi-ng: common: Don't call hw_to_ccu_common on hw without common

In order to set the rate range of a hw sunxi_ccu_probe calls

hw_to_ccu_common() assuming all entries in desc->ccu_clks are contained

in a ccu_common struct. This assumption is incorrect and, in

consequence, causes invalid pointer de-references.

Remove the faulty call. Instead, add one more loop that iterates over

the ccu_clks and sets the rate range, if required.
