boards: arm: adi: Enable display for MAX32662EVKIT board

Browse source 
MAX32662EVKIT board has CFAF128128B1-0145T display which
is 128x128 graphic display.
This commit enable mpi dbi display support with LVGL graphic library.
Pin connection of display is 3wire mode
SRAM size increased to be fit with lvgl example.
