Update pin control variable names to make common for all lpass varients.
Update bulk clock voting to optional voting as ADSP bypass platform doesn't
need macro and decodec clocks, these are maintained as power domains and
operated from lpass audio core cc.

Hi Srinivasa,
Thanks for the patches, I think you forgot to add correct mailing list 
for this drivers.

Please consider using scripts/get_maintainer.pl to help you with this list.

How are you going to ensure that the powerdomains are switched on when 
setting up the pinctrl configuration.

Should we not take a reference to the power-domain in this driver?

The required power domains are getting enabled in core-boot level. So no 
need of reference in this driver.

And still if power domain need to referenced, we can do it from device 
tree itself.
