drm/i915: Add support for Generic MIPI panel driver
This driver makes use of the generic panel information from the VBT.
Panel information is classified into two - panel configuration and panel
power sequence which is unique to each panel. The generic driver uses the
panel configuration and sequence parsed from VBT block #52 and #53
v2: Address review comments by Jani
- Move all of the things in driver c file from header
- Make all functions static
- Make use of video/mipi_display.c instead of redefining
- Null checks during sequence execution
v3: Address review comments by Damien
- Rename the panel driver file as intel_dsi_panel_vbt.c
- Fix style changes as suggested
- Correct comments for lp->hs and hs->lp count calculations
- General updating comments to have more clarity
- using max() instead of ternary operator
- Fix names (ui_num, ui_den) while using UI in calculations
- compute max of lp_to_hs switch and hs_to_lp switch while computing
hs_lp_switch_count
