Subject: [PATCH v4 0/3] Add startek-kd070fhfid015 display support

Add the support of the Startek KD070FHFID015 panel.
It's a 7-inch TFT LCD display with a resolution of 1024 x 600 pixels.

I use this display plugged to my mt8365-evk board.

This serie come from a bigger one [1]. Then I addressed the previous
comments for the related commits here.

Changes in v4:
- Remove useless function: stk_panel_shutdown.
- Align parenthesis for readability.
- Link to v3: https://lore.kernel.org/r/20230711-startek_display-v3-0-dc847e6b359b@baylibre.com

Changes in v3:
- Remove spurious line.
- Remove useless ops (enable and disable).
- Remove brightness value init because it is set right after
  using mipi_dsi_dcs_get_display_brightness(...).
- Link to v2: https://lore.kernel.org/r/20230711-startek_display-v2-0-87bc7bdec6e9@baylibre.com

Changes in v2:
- Replace "dcdc-gpio" by "enable-gpio" because this pin enable the
  Power IC supply. Also, this property come from panel-common.
- Remove height-mm and width-mm since they are useless here.
- Re-order elements in the stk_panel structure for readability.
- Link to v1: https://lore.kernel.org/r/20230711-startek_display-v1-0-163917bed385@baylibre.com

Changes in v1:
- Fix typos in the driver.
- Merge 2 regulators in one bulk variable in the driver.
- Remove backlight enable/disable from the driver because it's already
  managed by the backlight core.
- Move hardcoded values from function to the generic structure in the
  driver.
- Remove unnecessary function (stk_panel_del).
- Replace some functions by macro to increase the readability.
