Added changes to support generic power domain and opp table.
This is an alternative for downstream regulator framework.
power domain can be enabled using below dtsi entries.
power-domains =
<&videocc MVS0C_GDSC>,
<&videocc MVS0_GDSC>,
<&rpmhpd SM8450_MXC>,
<&rpmhpd SM8450_MMCX>
power-domain-names =
"iris-ctl", "vcodec", "mx", "mmcx";
Power domain handles willbe parsed at driver side using below api's.
- dev_pm_domain_attach_by_name()
- devm_pm_opp_attach_genpd()
devm_pm_opp_attach_genpd() provides consumer virtual device handles
and i.e linked to core->dev using device_link_add().
MXC, MMCX rails wilbe powered up by scaling desired rate using
dev_pm_opp_set_rate().
