Add CRG driver for Hi3798CV200 SoC. CRG(Clock and Reset
Generator) module generates clock and reset signals used
by other module blocks on SoC.

change log
v3:
- Added ethernet and combo-phy clocks.
v2:
- Fixed compiling error when compiled as a module.
- Fixed issues pointed by Stephen Boyd.
- Added prefix HISTB for clock index macro definitions.

Hi, is there any mainline kernel or uboot for hisilicon hi3520dv200 or
hi3520dv300? just want some base support to boot , anything close to
mainline is ok :)

can check it out and apply for the source code following the instructions.

And you should have signed it off? Care to resend or state that
this is incorrectly attributed to you instead of Pan Wen?

Pan Wen is the main author of this patch. I just made some small modification

Sure I'll apply the resent one. But you should also make sure to
retain Pan Wen's authorship. I'll go do that when applying it.
