Subject: [PATCH 1/2] soc: samsung: pmu: Remove unused and duplicated defines
The exynos-regs-pmu.h was never a complete list of PMU registers. It
contained a lot of holes for registers which are not used. However, a
lot of unused defines came with porting the code from vendor kernel.
Few of defines were also duplicated.
Remove them so the file will be slightly smaller.
