configs: spresense: add basic LCD configuration
* arch: arm: cxd56xx: add Graphics Engine
Add driver for hardware image processor device
to enable the hardware image processor set CXD56_GE2D=true
Signed-off-by: Alin Jerpelea <alin.jerpelea@sony.com>
* drivers: lcd: add ILI9340 LCD Single Chip Driver
LCD Single Chip Driver, ILI9340, ILI Technology Corp.
Required LCD driver settings:
LCD_MAXCONTRAST should be 255, but any value >0 and <=255 will be accepted.
LCD_MAXPOWER should be 1: 0=off, 1=on

JDI LPM013M091A LCD Driver.
This driver doesn't support reading data.
Recommended to use DMA to transfer data or displayed image would be
broken.
