Subject: [PATCH v1 3/3] clk: rockchip: add new pll-type for rk3328 and similar socs

The rk3328's pll and clock are similar with rk3036's,
it different with pll_mode_mask,there are different
adjust foctors and control registers,
so these should be independent and separate from
the series of rk3328s.
