Bintian Wang 72ea48610d clk: hi6220: Clock driver support for Hisilicon hi6220 SoC 
Add clock drivers for hi6220 SoC, this driver controls the SoC
registers to supply different clocks to different IPs in the SoC.

We add one divider clock for hi6220 because the divider in hi6220
also has a mask bit but it doesnot obey the rule defined by flag
"CLK_DIVIDER_HIWORD_MASK", we can not get index of the mask bit by
left shift fixed bits (e.g. 16 bits), so we add this divider clock
to handle it.
