drm/panel: ilitek-ili9806e: rename to specific DSI driver

The Ilitek ILI9806E controller can support different transport buses,
such as MIPI-DSI and SPI. The current implementation is specific to
the MIPI-DSI interface.

In preparation for adding SPI support, rename the current Kconfig
symbol and files to be DSI-specific, clarifying the current scope
of the code.

Since DRM_PANEL_ILITEK_ILI9806E is not used in any in-tree defconfig,
the symbol is renamed directly to DRM_PANEL_ILITEK_ILI9806E_DSI without
providing a legacy compatibility alias.
