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.

  Power IC supply. Also, this property come from panel-common.

- 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.
