MB1315 TFT LCD daughterboard

MB1315 is the TFT LCD daughterboard supporting RGB mode, available to mount on the
STM32L4R9I-EVAL main board via the CN1 connector.
The 4.3" TFT LCD uses LCD RK043FN48H-CT672B with a capacitive touch panel, which only
supports 3.3 V power and interface. So, a level shifter SN74LVC16T245DGGR is requested
on the TFT RGB LCD daughterboard to support a wide power supply range.
