Add support for E35GH-I-MW800CB 320x480 MIPI DSI panel by FocusLCDs.
The panel uses Ilitek ILI9488 driver IC in DSI mode specifically.
ILI9488 also appears in DBI/SPI panels, but those require different bus drivers.

This is a resend of v3. Since v3, this panel driver has been tested on 
STM32MP157D-DK1 in addition to TI AM62P EVK. The panel works in video mode on 
both platforms. Additional panels using ILI9488 DSI can be added later 
with their own timings.

v5: Switched to devm_drm_panel_add() and devm_mipi_dsi_attach()
    Dropped not required anymore .remove callback
    Added display_info.bpc=6 initialization
    Changed 0x21 DCS command to send 0 arguments as per spec

v4: Rebased
    Tested 7.1-rc5 on STM32MP157D-DK1
    Adjusted E35GH-I-MW800CB mode timing to a 14.4 MHz pixel clock with
    slightly increased blanking to make it more synthesizable across DSI hosts
