Some Poco F1 phones from Xiaomi have a FHD+ video mode panel based on the
Novatek NT36672A display controller; Add support for the same.

Most of the panel data is taken from downstream panel dts, and is converted to
drm-panel based driver by me.

It has been validated with v5.9-rc1 based drm-misc-next on Poco F1 phone; my tree with other
dependent patches is here [1]

v2: In dt-binding, removed ports node, making port@0 directly under panel@0 node.
     Also updated the panel_on delay to a safer 200ms as needed for latest Android.
v3: Replaced port@0 with just port in panel@0 node.
v4: Since "0425662fdf05: drm: Nuke mode->vrefresh", we have to calculate
     vrefresh on demand. Update for it.
v5: Fixed review comments from Sam:
      - rebased on top of drm-misc-next
           remove return of drm_panel_add()
           remove drm_panel_detach()
      - renamed the panel driver file to reflect that this is a novatek
           nt36672a display driver and not only for tianma panels.
           Adjusted some internal names also to reflect the same.
      - corrected changelog to add info about the generic Novatek DSI IC
      - corrected compatible string accordingly
      - removed pinctrl
      - used drm_panel* API for prepare/unprepare/disable/remove
v6: Fixed few review comments on v5 from Sam:
      - add dev_err_probe() support
      - move DRM_* error printing to dev_err()
      - removed a few unnecessary bits
v7: Fixed review comments on v6 from Bjorn:
      - Reworked the send_mipi_commands functionality
      - removed regulator disable_loads; moved active_load setting to probe
        time
      - made function names and struct less generic
      - updated the reset_gpio working to active_low
      - update MAINTAINERS for file name changes

This latest version (v7) had all the outstanding comments fixed, and
Bjorn has also given his r-b, so could you please get this set of
patches merged?
