boards: arm: stm32f429i_disc1: update onboard display

Browse source 
Onboard display is actually an ILI9341. It is connected to SPI5 which
is shared with L3GD20. Max clock is set as described in BSP driver files
(stm32f429i_discovery.c@638). ILI9341 configuration updated to enable
RGB interface use.
