[v2,13/38] ARM: EXYNOS: pm_domains: Remove legacy power domain registration code

Commit Message

Tomasz Figa June 17, 2013, 4:33 p.m. UTC

This patch removes static definitions of power domains and code
responsible for registering them and adding devices to them, since only
DT based boot is now supported on Exynos.
