*of_iomap()* will check the device node pointer, and if the pointer is
NULL it will return error code. So refine clock's init flow by checking
the device node with this simple way; and polish a little for the print
out message.

Clock provider drivers generally shouldn't include clk.h because
it's the consumer API. Remove the include here because this is a
provider driver. Also drop the clkdev.h include in files that
aren't using it.

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.

Remove the static variable. So these common clock register helper could
be used in more SoCs.

Enable common clock driver of Hi3620 SoC. clkgate-seperated driver is
used to support the clock gate that enable/disable/status registers
are seperated.
