[PATCH v3 4/4] clk: rockchip: rk3368: make some special clk as critical_clocks

[Elaine Zhang]

The jtag clk no driver to handle them.
But this clk need enable,so make it as critical.

The ddrphy\ddrupctl clks no driver to handle them,
Chip design requirements for these clock to always on,
The new document will update the description of these clock.

The pmu_hclk_otg0 is Chip design defect, must be always on,
The new document will update the description of this clock.
