To this end, a new "bypass_reg" was introduced. In addition, when calculating rate, the PLL of X1830 introduced an extra 2x multiplier, so a new "rate_multiplier" was introduced. And adjust the code in jz47xx-cgu.c and x1000-cgu.c, make it to be compatible with the new cgu code.

"X1000_CLK_SSIPLL_DIV2" is added for this purpose, it must between "X1000_CLK_SSIPLL" and "X1000_CLK_SSIMUX", otherwise an error will occurs when initializing the clock. These ABIs are only used for X1000, and I'm sure that no other devicetree out there is using these ABIs, so we should be able to reorder them. 2.Clocks of LCD, OTG, EMC, EFUSE, OST are also added.
