drm/i915/vlv: Make the vlv_dpio_read/vlv_dpio_write more PHY centric
vlv_dpio_read/write should be describe more in PHY centric instead of display controller centric. Create a enum dpio_channel for channel index and enum dpio_phy for PHY index. This should better to gather for upcoming platform. v2: Rebase the code based on drm/i915/vlv: Fix typo in the DPIO register define. v3: Rename vlv_phy to dpio_phy_iosf_port and define additional macro DPIO_PHY, and remove unrelated change.
