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 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.
v6: Rebased
No functional changes
v5: Rebased
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
