To support ufs #1 for Exynos Auto v9 SoC, we need to control its own pmu
register. So, we need to specify the offset of the register via an
argument of syscon node.
Regarding UFS HCI driver, we need to specify different sysreg
configuration for UFS #1's io coherency setting.

Changes from v1:
- dt-bindings: Correct tab align and add "minItems: 1" to make the second
  cell as optional.
- Add 0001- patch to constify phy_cfg.
- Allocate phy->isol and copy data from drvdata to avoid const qualifier
  error
- Add 0004- patch to apply dt style for ufs0 as Krzysztof's suggestion
- Align tab and apply ufs node naming for device tree nodes

Chanho Park (6):
  dt-bindings: phy: samsung,ufs-phy: make pmu-syscon as phandle-array
