clk: qcom: Constify struct pll_vco

pll_vco structure are never modified. They are used as .vco_table in
"struct clk_alpha_pll".

And in this structure, we have:
	const struct pll_vco *vco_table;

Constifying these structures moves some data to a read-only section, so
increase overall security.

On a x86_64, with allmodconfig:
