Samsung SoC drivers for v6.19, part two

Two fixes for Exynos PMU (Power Management Unit) driver:

1. Silence lockdep warning being actually a false positive, but quite
   disturbing during testing.  Issue was introduced in v6.18.

2. Drop device refcount when requesting device regmap with
   exynos_get_pmu_regmap_by_phandle().  Issue was introduced much
   earlier (around v6.9), with code being rewritten in between.
