[Intel-gfx] [RFC 1/6] drm/i915: Create PPS related struct and func pointers

[Vandana Kannan]

Creating generic functions and data related to panel power sequencing in
intel_panel. The functions have been added equivalent to
intel_dp_panel_power_sequencer() and intel_dp_panel_power_sequencer_registers()

These changes have been made to move PPS related data from intel_dp or
other panel types to generic intel_panel.

Note:- Although edp_power_seq is used as a return type in the functions,
the structure can be made generic for all panels.
