[v3,0/2] add device managed version of dev_pm_domain_attach|detach_list()

These patches add the devres-enabled version of
dev_pm_domain_attach|detach_list in pm domain framework and
use the same APIs in venus driver.

If any client drivers use devm_pm_domain_attach_list() to
attach the PM domains, devm_pm_domain_detach_list() will be
invoked implicitly during remove phase.

Changes since v2:
 - made devm_pm_domain_detach_list as static and no
   longer export this API.
 - added null checks for num_pds to avoid adding a 
   devres callback for the same.
 - added bryan's reviewed-by from v1.

Changes since v1:
 - fixed the warnings reported by kernel test robot.
 - added stub functions for !CONFIG_PM case.
 - removed un-necessasry type casting.
 - fixed the issue with remove sequence.
