drm/panel/panel-ilitek-ili9806e: Add Densitron DMT028VGHMCMI-1D TFT to ILI9806E DSI TCON driver

Add Densitron DMT028VGHMCMI-1D 480x640 TFT matrix 2.83 inch panel
attached to Ilitek ILI9806E DSI TCON into the ILI9806E driver.

Note that the Densitron panels use different TCONs, this driver is for
the later panel, use panel-ilitek-st7701.c for the former panel:
DMT028VGHMCMI-1A - ST7701
DMT028VGHMCMI-1D - ILI9806E
