Use clk_bulk interface instead of the orginal one to simplify the code.
For SMI larbs: Require apb/smi clocks while gals is optional.
For SMI common: Require apb/smi/gals0/gal1 in has_gals case. Otherwise,
also only require apb/smi, No optional clk here.
About the "has_gals" flag, for smi larbs, the gals clock also may be
optional even this platform support it. thus it always use
*_bulk_get_optional, then the flag has_gals is unnecessary. Remove it.
The smi_common's has_gals still keep it.
Also remove clk fail logs since bulk interface already output fail log.

Hello Yong,
thanks for the patch! However, I have an improvement to point out:

This refers to mtk_smi_common_clks[] and should be probably moved after that.
In any case, I don't think that there's any need to manually define this as 4,
as you can simply use the macro ARRAY_SIZE(mtk_smi_common_clks).
Using that will make you able to not update this definition everytime an update
occurs to the mtk_smi_common_clks array.

Whoops. Sorry for that.
I'll send a patch to address what I pointed out, unless the original author of
this series wants to.
Thanks,
